MPR Menu

The MPR menu of the MPR window provides additional functionality concerning loading and management of 3D CT (and MRI) imaging series.

MPR Image Set #1 - Selects image set #1 as the active image set. This is the default image set. If you are using only a single set of axial images (e.g. CT images), load them as set #1. This will assure backwards compatibility of your treatment plan with earlier versions of PS that only supported a single image set.
MPR Image Set #2 - Selects image set #2 as the active image set. If an alternative set of axial images (e.g. MR images) is loaded into set #2, segmented controls will be added to the toolbars of windows that display reconstructions as a convenience to rapidly switch between the two axial image sets.
Reconstruction Options - use this hierarchical menu to customize MPR display options.
PSImage Capture Size - this hierarchical menu selects the size (in pixels) of static image captures. Static image captures work best for treatment planning purposes with a 4:3 (horizontal:vertical) ratio of pixels at about 72 ppi.
PSImage Capture Range - this hierarchical menu selects the horizontal range (in mm) of static image captures. Static image captures work best for treatment planning purposes with a horizontal range of about 60 mm.
Planes... - Opens the MPR Planes sheet in which you can review the planar reconstruction transforms. This menu item is enabled when the MPR window is in 4 or 6 pane multiplanar reconstruction layout.
Meta-Data... - Opens the MPR Meta-data sheet in which you can review and customize the 3D-MPR series modeling parameters that were intialized from preference settings and/or meta-data tags found in the DICOM files. As a convenience, you can also open the Meta-Data sheet by double clicking in the MPR window when it is in single pane image series layout.
Clear All - Reinitializes the currently active (ie selected) image set to an empty set.

Reconstruction Options

Planar - crosshair and tool overlay options for planar reconstructions.
Spheroidal - monochrome and pseudo color options for spheroidal surface reconstructions.

Planar Options

Slice Crosshair - always show the ruler crosshair on slices in single pane layout.
MPR Crosshairs - show the eye centering crosshair when in 6-pane reconstruction layout. The appearance of the centering crosshair will add detail as you "zoom-in" on the eye.
MPR Histograms - overlay a histogram of the 8-bit gray levels under the eye centering crosshair. The histogram will become visible as you "zoom-in" on the eye. Histogram symmetry can help to find the geometric center of the eye.
Centering Circles - add centering circles to the eye centering crosshair.
Annotations - add annotations to slices and the axial reconstruction.
Calibration Rulers - add green calibration rulers to slices and reconstructions in the manner of OsiriX reconstructions.
Measurement Rulers - enables display of up to 8 distance measurement rulers. Double-click on a ruler to open the ruler properties sheet.
Orientations - Add orientation codes to slices and reconstructions.
Eye Model - Add a more detailed eye model to the eye centering crosshair when in 6-pane reconstruction layout.
Retina - Adds the inner sclera to the eye centering crosshair.
Nerve - Enable disc and nerve modeling.
Lens - Enable lens modeling.

Spheroidal Options

Monochrome - map the reconstruction with a monochome display palette.
Pseudo Colors 1 - map the reconstruction with a pseudo color display palette.
Pseudo Colors 2 - map the reconstruction with a pseudo color display palette.
Pseudo Colors 3 - map the reconstruction with a pseudo color display palette.
Pseudo Colors 4 - map the reconstruction with a pseudo color display palette.
Custom Colors - map the reconstruction using the customizable pseudo color palette defined in Images Preferences.

PSImage Capture Size

You may optionally capture reconstructions as static images for display in Plaque Simulator's Image window and/or printing as pages of Plaque Simulator's Images document. For treatment planning purposes, static images work best with a 4:3 aspect ratio and resolution of about 1024x768 (XGA) pixels.

800x600 - capture static images with a resolution of 800x600 pixels (SVGA).
1024x768 - capture static images with a resolution of 1024x768 pixels (XGA).
1200x900 - capture static images with a resolution of 1200x900 pixels.

PSImage Capture Range

50 mm - capture static images with horizontal range of 50 mm.
60 mm - capture static images with horizontal range of 60 mm.
70 mm - capture static images with horizontal range of 70 mm.
