Introduction

The LEADTOOLS Medical Image Viewer Control C++ Class Library allows you to incorporate Image Viewer Control functions into your applications. It provides support for displaying one or more images and for the real-time manipulation of one or more images. The LEADTOOLS Medical Image Viewer Control C++ Class Library functions are included with the LEADTOOLS PACS Imaging toolkit.

This C++ Class Library is a high-level component for building medical display applications such as DICOM viewers, view stations, Teleradiology solutions, and high-end diagnostic workstations found in radiology and other medical specialty departments. When building a PACS for radiology, cardiology, mammography, ophthalmology, pathology, dermatology, dentistry or any other specialty, this control will eliminate project complexity and provide a solid, reliable foundation for the PACS application.

Typical applications that can be built using this control include:

High-end medical diagnostic workstations.
Medical review and quality assurance stations.
DICOM viewers.
Light-weight viewers typically distributed on CDs with patient studies/series.
Web-based medical viewers.

Key Features:

Display medical grayscale and colored images, including MRI, CT, Digital X-Ray, and Ultrasound images.
Adjust the screen layout either manually or programmatically. For example, you can display two different image series side-by-side, each having a different scaling factor.
Display overlay information on images, with full control over the display text and its positioning inside each window. Includes built-in overlays such as window center and window width values, as well as field of view.
Control a display container's properties, such as its colors, cursors, window leveling, unit of measure, and rulers.
Use built-in image manipulation tools to perform different actions, as follows:

Window leveling (adjusting brightness and contrast).
Panning or moving an image.
Magnifying an image.
Stacking or moving from one image to another in a series using single key or single click actions.

Use the following built-in drawing tools:

Annotation tools: Arrow, Text, Rectangle, Ellipse, Ruler, Highlight, Angle. The ruler scales to the image's DPI and zoom or scale factor.
Region tools: Rectangle, Square, Ellipse, Circle, Polygon, Free hand, Magic wand, Color range, Nudge tool, Shrink tool.

Adjust the following settings for each tool:

Mouse button controls
Keyboard (hotkey) controls
Cursor display icons

Apply effects, as follows:

Apply effects to a single image, or to all images in the series
Apply effects to a single series or to all series managed by the control
Apply effects programmatically or through user interaction.

Assign a single action to multiple buttons.
Repaint the image more quickly by using the Low memory capability.
Display animations.
Use interpolated image display for higher quality.
Maintain compatibility with older 8-bit image displays.
Remove image regions.
Print cells.
Scale cells.
Use different image modes (fit a cell’s image to its cell height or cell width).

The demo is capable of performing photometric interpretation, and can display Monochrome1 and Monochrome2 images.
