DICOM Dataset:
A Data Set is a collection of Data Elements stored in a DICOM file. Each DICOM file may or may not include a header consisting of a Preamble and a Prefix. Each DICOM file represents a separate class of information. For example, one DICOM file may represent the Computed Tomography Image class, and another DICOM file may represent the Radiotherapy Structure Set class. DICOM Standard defines a vast numbers of Class Information Object Definitions as standard classes. LEADTOOLS supports user-defined classes in addition to the standard classes.

For each class supported by DICOM there are certain modules contained in each class. Each module consists of a number of Data Elements, each Data Element having its own tag. These Data Elements can be mandatory or optional, depending on the module and the class. In addition to the standard modules and data elements supported by DICOM, user-defined modules and data elements are also supported by LEADTOOLS.

LEADTOOLS maintains the Data Set internally as a tree structure and provides functions to evaluate the Data Set as a tree or as a list. The developer can create the data set object with all the appropriate elements for the specified class in one function call. LEADTOOLS Medical Imaging toolkit provide a number of functions for maneuvering through the Data Set, getting and setting Data Set information, getting and setting Data Element values, searching the Data Set, and creating, loading and saving Data Sets. LEADTOOLS provides functions to delete individual items, delete entire modules, delete all items and delete one or more images in a Data Set.

To retrieve and store values in the Value Field of the Data Element in a Data Set, LEADTOOLS provides low-level and High-level functions.

What are Value Representations (VR's)?
The value representation of a data element indicates the type of data that can be stored in the value field of the data element. There are a number of value representations that are standard for the DICOM. In addition to the standard value representations, user-defined value representations may also be added using LEADTOOLS.

LEADTOOLS maintains a table (or list) internally along with the code, name, length, restrictions and unit size of all available standard and user defined value representations. LEADTOOLS also provides functions to get, set, delete, and rename the value representations in the table.

What are Data Elements and Tags?
The tag of a data element consists of an ordered pair of 16-bit values that represent a Group number and an Element number. The tag indicates the type of information stored in the value field of the data element. There are a number of tags that are standard in DICOM. In addition to the standard tags, user-defined tags may also be added using LEADTOOLS.

LEADTOOLS maintains a table (or list) internally of all available standard and user-defined tags, including the tag's code, name, value representation and value multiplicity information. LEADTOOLS provides a number of functions for maneuvering through, adding, deleting and modifying the Data Element Tag table. Also Data Element table allows the developer to add support for future Data Elements in DICOM without having to receive an upgrade from LEADTOOLS.

What do Unique Identifiers (UIDs) identify?
A unique identifier identifies items such as Service-Object Pair Classes and images. There are a number of unique identifiers that are standard for the DICOM file format. In addition to the standard unique identifiers, user-defined unique identifiers may also be added using LEADTOOLS.

LEADTOOLS maintains a table (or list) internally of all available standard and user-defined unique identifiers, with the UID's name, value and type information. LEADTOOLS provides a number of functions for maneuvering through, adding, deleting and modifying the UID Table.

What is an Information Object Definition?
An Information Object Definition (IOD) is an abstract data model that specifies information about Real-World objects. It provides a means of standardizing information exchanged between applications. There are a tremendous number of IODs that are standard in DICOM. In addition to the standard IODs, user-defined IODs may also be added using LEADTOOLS.

LEADTOOLS maintains a tree internally of all available standard and user defined Information Object Definitions (IODs). LEADTOOLS' functions allow you to evaluate the internal IOD Structure as a tree or as a list.

LEADTOOLS provides a number of functions for maneuvering through and modifying the IOD Structure such as GetRoot, GetParent, GetChild, GetFirst, GetLast, GetCountModule, etc... The toolkit provides several functions for searching the IOD Structure to insert new items, delete individual items and change the name or the description of an IOD already in the IOD Structure. A developer can use the IOD Structure to validate a DICOM Data Set. Additionally, the IOD table Structure allows user to add support for future IODs in DICOM with the current version of LEADTOOLS.

What are DICOM Basic Directories (DICOMDIR)?
In order to identify a DICOM file-set and to facilitate accessing the information stored in the DICOM files of the file-set, the DICOM standard has defined the Basic Directory IOD. A DICOM file-set contains one or more DICOM files. One of the files contained in the file-set is the DICOMDIR file. The DICOMDIR file contains DICOM Directory information, making it easier to access the information contained in the other DICOM files in the file-set. The DICOM files in the file-set are assigned File IDs; so, they can be referenced by the DICOMDIR File, which itself, is identified by a File ID of DICOMDIR.

DICOM Dir data sets may contain special data element called key elements. A Key element is a data element that also contains special information about other key elements in the data set and their relative location within the data set. The specialized information included in a key element maintains information on key element children, non-key element children, parent key elements, and the logical relationships between the elements.

LEADTOOLS maintains the DICOMDIR data set as a tree; however, all key elements are stored at the same level of the tree. LEADTOOLS provides special functions for searching the DICOM Dir data set, maneuvering through the data set, inserting and deleting key elements, and manipulating key elements.

LEADTOOLS also provides high-level functions to create or update DICOMDIR by adding DICOM files or DICOM Data Set loaded in the toolkit.

DICOM Waveforms:
The DICOM standard supports waveform storage and communication: this includes hemodynamic curve data, cardiac electrophysiology, electrocardiography (ECG) and audio signals (WAV files).

LEADTOOLS waveform support is comprehensive and handles the various features supported by the standard which include:

• Management of Waveform Group attributes
• Channel Manipulation (setting/getting channel samples, source, sensitivity and other attributes)
• Audio Support (with the ability to create Basic Voice Audio files for report dictation)
• Waveform annotations

In addition, LEADTOOLS supports the different waveform-related IODs defined by the standard which include:

• Basic Voice Audio
• 12-Lead Electrocardiogram
• General Electrocardiogram
• Ambulatory Electrocardiogram
• Hemodynamic

DICOM Annotation:
LEADTOOLS medical programming SDKs offer a variety of annotation (image markup) options that can be added to medical, grayscale and color images.

Annotation objects available include Ruler, Protractor, Cross Product, Pointer, Text, Circles, Freehand, etc. LEADTOOLS allows you to read or write annotations as an external annotation file, private DICOM data elements or LEAD or Wang annotation tags within a TIFF file, or annotations can become a permanent part of the image data or applied to a 1-bit image to create an overlay. With LEADTOOLS Annotations, you can choose between low level access to the annotations, or you can implement annotation support through a fully automated mode with a ready to use floating, customizable toolbar and pop-up menus. The superior annotation features provided in LEADTOOLS can be used in any application where image markup is desired.

LEADTOOLS allows the end-user to reposition nodes of an existing freehand object, which prevents the user from having to redraw the object. Enhanced redact objects allow you to restore parts of an image that were blacked out. When combined with annotation security, these redact objects provide a means of granting user-level access to parts of an image. Annotation objects can be stored as a separate object layer, or can be burned or embedded into the actual image. LEADTOOLS allows you to read or write annotations as an external file or as LEAD or Wang annotation tags within a TIFF file. With LEADTOOLS, you can choose between low level access to the annotations, or you can implement annotation support through a fully automated mode with a ready to use floating, customizable toolbar and pop-up menus. The superior annotation features provided in LEADTOOLS can be used in any application where image markup is required.

With LEADTOOLS Annotation support you can:

• Create any of the following objects: line, arrow, rectangle, square, ellipse, circle, polygon, freehand line, text, highlighter, hot spot, note, stamp, redaction, button, audio clip, video, freehand hot spots, points, protractors, cross-products, push pins, and rubber stamps

JPEG2000 Compression:
LEADTOOLS JPEG2000 compression/decompression conforms to the JPEG2000 International Standard. This new state-of-the-art ISO/ITU still image compression standard provides a fast and flexible solution for high-quality, wavelet-based compression. LEAD has committed to fully support all future parts as they are released and therefore LEADTOOLS JPEG2000 will continue to grow as the JPEG2000 standard grows.

LEADTOOLS JPEG2000 Features currently supports:

• Native support for 8, 10-16 bit grayscale and 24 bit color lossy compression in a DICOM dataset
• Adds intrinsic DICOM JPEG2000 16-bit grayscale lossy compression support to LEADTOOLS Medical Imaging. (JPEG2000 is the only 16 bit grayscale lossy compression supported by DICOM)
• Native support for 8, 10-16 bit grayscale and 24 bit color lossless compression in the DICOM dataset
• Signed 10-16 bit grayscale image data as supported by JPEG2000
• Easily convert DICOM datasets to and from JPEG2000 transfer syntax to and from any other transfer syntax included in DICOM 3 (2003 file standard) (except JPEG LS) using built in LEADTOOLS functions
• Improved network performance and image quality as compared to JPEG
• Support for four progressive display methods:
• • Quality Axis - The image starts blurred and the sharpness increases as more image data is received
  • Resolution Axis - The image is loaded as a smaller version and the physical pixel size increases as more image data is received
  • Color Axis - The image is loaded one color plane at a time. The image starts loading as a grayscale image and the color will fill in as more image data is received
  • Position Axis - The image is loaded as blocks. As more image data is received, more blocks are displayed
• Multiple resolutions can be stored in the same file without duplication of the image data providing the ability to only decode and display the size of image required by the application
• Error checking and robustness allows the transmission of JPEG2000 encoded files over a noisy medium. If an error occurs in the decoding, the image will still be displayed
• Control over the final size of the file without hit and miss quality factor adjustments

JPEG2000 compared to JPEG:
JPEG2000 is a new image-encoding standard that provides a feature set vital to the medical imaging community. JPEG2000 provides high compression with image quality superior to all existing standard encoding techniques. This high compression and quality performance is due to the adaptation of wavelet transforms. Wavelet transforms are mathematical formulas that represent complex structures in the image, thereby compressing an extremely large amount of image data into a relatively small amount of compressed data. This compression technique allows applications to save compressed images with higher compression ratios and better image quality as compared to any other software currently in production.

JPEG2000 is a wavelet-based compression stored in a hierarchical format which can contain several stored resolutions of the image in the same file without duplication of data. For that reason, a JPEG2000 compressed image can then be sent to a device in the resolution that best fits without additional storage overhead. LEAD Technologies has used its more than twelve years in the imaging and compression developer toolkit marketplace to formulate a JPEG2000 product that offers DICOM developers the best JPEG2000 implementation available.

JPEG2000 Key Benefits:

• Greater compression while maintaining better quality than traditional JPEG. This helps reduce network bandwidth and storage requirements.
• JPEG2000 is the only 16-bit grayscale lossy compression supported in DICOM
• Maintain diagnostic image quality by using JPEG2000
• Multiple resolutions in JPEG2000 means that only the data needed to view the image for a particular device or zoom need be sent over the network and loaded into memory
• Progressive display provides feedback to the user while the image is loading
• Region of interest encoding and decoding. Compress specified areas of the image more or received more detail for an area of interest on the client maximizing network efficiency while providing the user the detail that he or she demands
• JPEG2000 supports 24 bit color, and 8, 12 and 16 bit grayscale image data
• LEADTOOLS supports JPEG2000 on multiple platforms including Windows, Pocket PC and an Internet Explorer plug-in

Grayscale Imaging:
Grayscale is a range of shades of gray without apparent color. The darkest possible shade is black, which is the total absence of transmitted or reflected light. The lightest possible shade is white, the total transmission or reflection of light at all visible wavelengths. Intermediate shades of gray are represented by equal brightness levels of the three primary colors (red, green and blue) for transmitted light, or equal amounts of the three primary pigments (cyan, magenta and yellow) for reflected light.

The LEADTOOLS Medical Imaging product line offers complete support for 8-16 bit grayscale, and 12 and 16 bit image processing and display with window leveling and LUT processing.

LEADTOOLS Document and Medical Imaging SDKs include the following grayscale functionality:

• Grayscale Image Display
• Grayscale Image Processing
• Grayscale Common Dialogs
• Grayscale Signed Images
• Grayscale Compression - JPEG Lossy/Lossless, JPEG2000

Grayscale Image Processing:
LEADTOOLS includes a number of medical image processing functions. Below is a list of key image processing features focused on the medical imaging community and is not a comprehensive list of functionality. If there is a particular image processing function that you need, but can not find below, LEADTOOLS probably supports it. Contact sales@componentsource.com for information.

• Get Functional Lookup Table Updates a range of entries in a lookup table, based on specified mathematical functions such as exponential, natural logarithm, linear
• Get User Lookup Table Updates a lookup table, based on a curve that passes through specified points
• Get Min and Max Bits Returns the low and high bits of the values present in a 12 or 16-bit grayscale or 48 or 64-bit color image
• Get Min and Max Values Returns the minimum and maximum intensity values present in a 12 or 16-bit grayscale or 48 or 64-bit color image
• Combine Combine performs logical or mathematical operations to merge the image data from two images to create a new image. Source and destination areas, color planes (R or G or B or R, G, and B) to combine as well as the operations to use on the data are specified by the user. Combine can be used to add or subtract overlay bits(plane) to an image
• Add or average list of images Noise can be reduced by averaging a list of images together. Adding a list of images together can be used to show details in low intensity areas of an image
• Spatial Filters Spatial Filters can be used for line detection, point detection or to smooth high spatial frequencies (low pass filter), and specialized image processing for CAD (Computer Aided Diagnosis). Use one of several predefined spatial filters or specify a user-defined spatial filter kernel (matrix)
• Intensity Detection Intensity detection is used to threshold an image based on intensity. Thresholding can be helpful in measuring objects such as a tumor in an image
• Contour Filter Contour filter is a type of morphological binary filter used to get the outline of objects in an image. The outline created by the contour filter can be useful for object measurement
• Binary Filters Binary filters can be used for the erosion or dilation of objects or removal of noise in an image and can also be used for area measurement
• Edge-detection Filter The Edge-detection filter detect edges in an image by looking for sharp contrast changes and can be useful for object measurement. Additionally, the edge-detection filter can be used to sharpen or enhance edges in an image when used in combination with Combine
• Median Filter The Median filter can be used to remove negative exponential, and salt and pepper type of noise while preserving the edge details within an image
• Histogram Histogram provides information about the image concerning the intensity or gray-level distribution of pixels. This information can be used for many image corrections for the proper display of the image
• HistoContrast Increases or decreases the contrast of the image, using a histogram to determine the median brightness as opposed to using an arbitrary value of 128. This function finds the median brightness of the image, then brightens the pixels with values above the median and darkens the pixels with values below the median
• HistoEqualize Linearizes the number of pixels in an image based on the specified (RGB, YUV or GRAY) color space. This can be used to bring out the detail in dark areas of an image
• Stretch Intensity Increases the contrast in an image by centering, maximizing, and proportioning the range of intensity values. Unlike ordinary contrast, Stretch Intensity always retains the original number of different intensity values. (Ordinary contrast adjustments can lose values at the high and low ends of the scale.)
• Unsharp Mask Unsharp mask is a technique to enhance the edges of an image. Unsharpen mask tends to show more details in areas of an image that are normally not visible
• Anti-aliasing Filter Anti-aliasing filter is used to smooth edges in an image and smooth jagged diagonal lines
• Gaussian Blurring Gaussian blurring is a noise reduction technique that employs a mean filter to remove high spatial noise and blurs the edges within an image
• Balance Colors Redistributes the RGB values of the image, using values specified for each color channel
• Change Hue Change the hue of the image by rotated the hue wheel a specified number of degrees
• Change Saturation Increase or decrease the color saturation in an image
• Color Inversion Inverts the colors in the image so that a positive image becomes a negative and a negative image becomes a positive
• Swap Colors Swap color channels in an image

Region of Interest (ROI)

• Create a region based on a specific color or intensity
• Create a region based on RGB or HSV color range
• Create rectangular, elliptical, polygonal and rounded regions
• Create region with from seed pixel and threshold (magic wand)
• Create curved regions or add a curved region to an existing region
• Convert standard curved regions to Bezier curves

Use low-level functions to change parts of an image as follows:

• Get and put rows of image data
• Get and put parts of rows
• Get and put the colors of individual pixels
• Process a region within a bitmap

DICOM Digital Signatures:
Digital signatures are used to verify the identity of the signer and to ensure that the signed data has not been altered or destroyed in an unauthorized manner. LEADTOOLS is the first commercial toolkit to add comprehensive support for the DICOM Digital Signature Profiles , which include: "Base RSA Digital Signature Profile", "Creator RSA Digital Signature Profile" and "Authorization RSA Digital Signature Profile".

With the complete LEADTOOLS support for Digital Signatures you can easily perform the following:

• Create Digital Signatures in the main Data Set as well as in an Item of a Sequence of Items; you can specify the MAC Calculation Transfer Syntax UID, the MAC Algorithm, the Data Elements to be signed, and the Digital Signature Security Profile to conform to
• Verify a single Digital Signature or all the Digital Signatures in the whole Data Set at once
• Get information about a particular Digital Signature
• Enumerate the Digital Signatures in the main Data Set as well as in an Item of a Sequence of Items
• Search the Data Set for a specific Digital Signature

General Imaging Features:
LEADTOOLS Medical Imaging adds 8-16 bit grayscale support, and 48 and 64 bit color functionality to the Raster Imaging Pro features to make the Medical Imaging a complete imaging solution. Other general imaging features include: Image Processing, Color Conversion, Display, Special Effects (choose from more than 2000 effects), Compression, Image Format (import/export), Printing, Internet/intranet imaging (Web Forms), Database imaging, Imaging Common Dialogs and Screen Capture.

Image Display, Memory and Processing Optimizations (Bitonal Scaling): (*Only available in LEADTOOLS Document Imaging or Medical Imaging Toolkits. †Only available in LEADTOOLS Medical Imaging Toolkits.)
LEAD Technologies continually reviews and adds file format support to give your application control over the display of almost any Raster or Vector image (only available in LEADTOOLS Vector Imaging SDK) you encounter. LEADTOOLS currently supports over 150 different image formats and sub formats, each of which has its own unique set of load/save/display options, which may encompass varying types and/or degrees of compression, a range of image information bit-depths, progressive (multi-pass) image display, the ability to maintain multi-page or multi-channel images, animations, or non-image data, just to name a few. You can depend on LEAD Technologies to provide you with the support you need to give your application control over the display of almost any image you encounter. Image display can be subdivided into two groups: raster image display and vector image display. These groups are described in more detail in the following sections.

Raster Image Display
LEADTOOLS provides numerous functions to let you take control of your application's image display. Control brightness and contrast settings, color reduction with dithering and palette control, scaling/fitting, enlargement/reduction, panning, scrolling, painting with transparency and/or regions.

Further, LEADTOOLS provides high level image-list and thumbnail browser controls, a special magnifying-glass feature, an automated pan-window control, and a Zoom View control that allows you to annoate pre-defined zoomed regions.

Key Features

• Intensity, contrast and gamma correction - LEADTOOLS renders an image of any color depth (1 to 64 bit † ) to any display device, automatically handling any color reduction or expansion. Changes can be applied to the display without affecting the original data. If desired, color reduction and display settings can be rendered into the image (See Image Processing). You can render images with a color specified as transparent.
• Dithering - Images can be automatically dithered to match the output display device on the fly, without changing the image in memory. Specify the dithering method for images that have more bits per pixel than the current video mode. The following are options can enhance the quality of your image display:
• • Normal dithering (using error diffusion).
  • Ordered dithering, faster but less accurate than normal.
  • [DLL only] No dithering, which relies on the display device for color reduction.
• Position and Scale - Position the displayed image, and zoom in or out (enlarge or reduce) by scaling and clipping. Use nearest neighbor (fastest), bilinear (fast-good quality) or bicubic (best quality) resampling for enlarged/reduced display size. Specify a source rectangle (portion of source image to paint) and destination rectangle (position on screen or drawing surface on which to paint it) for complete control over image zoom and position. Or, specify higher level properties like ZoomFactor (fit-to-window preserving aspect ratio, stretch to entire window, fit-to-width, 1:1 normal display).
• Display Enhancement - Using our Document and Medical toolkits, when displaying 1-bit (black-and-white) images, to enhance the quality of display you can:
• • Specify a scale-to-gray option *, which increases the clarity of the 1-bit images when they are scaled (zoomed out).
  • Specify a favor-black option *, which prevents loss of details, such as fine lines, when an image is scaled down (zoomed out).
  • The rotated display feature allows rendering images rotated in 90-degree increments without changing the image in memory. Large 1-bit images can remain compressed in memory while decompressing only the portion needed for display*.
• Automated Controls - When working with the ActiveX, COM, or .NET controls, you can set properties which determine the way that images are displayed in the control, such as AutoScroll (automated scroll bars), AutoSize (snap control to image), PaintSizeMode (1:1 scale, fit image to control, zoomed at specified magnification factors).

When used with the AutoScroll option, all Scroll Bar activity is automatic (scroll bars respond to programmatic changes of display settings, and display settings are updated by user's use of scroll bars).

• Palette Control - If the display mode is 256 colors or less, you can use a palette already associated with the image, or use a fixed palette to eliminate palette (color) shifting when displaying more than one image at a time.
• Image List and Thumbnail Browser Controls - Display and manipulate a list of images as an array of thumbnails using the ImageList Control, or use the Thumbnail Browser for browsing entire directories of image files.
• Pan Window - The automated pan window enables navigation through a large image using a small thumbnail view.
• Zoom View - Our Document and Medical toolkits include a Zoom View control that allows you to display and/or annotate multiple pre-defined zoomed regions.
• Regions of Interest - Display an automated rubberband (rectangle, ellipse or freehand) to mark an area and create a region of interest.
• • Paint an image only in a selected region of interest, or paint an image with transparency (any pixels which are the selected transparent color are not painted).
  • Zoom in on a selected area. Use with automated rubberbanding for entirely automated behavior, or specify selected area in code.
• Drawing - Define the client area of a LEAD control as a display surface where you can use Windows graphics device interface (GDI) functions for drawing or adding text. (You can also get a display surface derived from the actual image stored in memory in order to use Windows GDI to draw permanently into the image - see Image Processing: Drawing.
• Apply Effects - Apply any of over 2000 Special Effects, such as wipes, fades, dissolves, transitions commonly used in slide presentations.
• Complete Control - When painting images on any video device, you can:
• • Selectively force repainting of the image in a LEAD control to avoid unnecessary repaints, or use AutoRepainting to automate all display updates.
  • Limit the area to be painted by specifying the source and destination clipping areas (independent of source and destination rectangles which position image on screen).
  • Use Double Buffer painting to eliminate flicker when painting.
  • se a buffer as the source to paint. (Can be used, for example, to paint an image as it is being loaded)
  • Specify an option for fast painting (without device error checking).
  • Apply ROP codes, which determine how to interact with the existing image on the screen. (not supported in .NET).
