VolumeViz Medical MPR Viewer

Medical MPR Viewer Summary:

    This example shows a number of display and interaction techniques combined to create a basic DICOM MPR (4 view) viewer using multiple viewports.

    This example is effectively the same as the MedicalMPRViewerRemote example except running as a desktop application.

    Primary features include:

    • 3D Volume rendering view plus Axial, Coronal and Sagittal slice views.
    • View layout can be changed.
    • Any view can be "maximized" to fill the window.
    • Camera and window center/width are synchronized for slice views.
    • Supports both mouse input and touch input (on a touch screen device).

    Secondary features are similar to the DicomImageViewer demo:

    • DICOM information (patient, study, series, etc) is displayed using screen locked annotation text.
    • The image number and number of images are displayed.
    • The window level and width values are displayed.
    • Orientation markers are (letters near edge of window) are displayed.
