To switch between modes, the Switch render mode button on the toolbar is used.
Four render modes are available:
The MPR mode. Sections are available for viewing. Set by default.
The MIP mode . A slice of a particular thickness is viewed instead of a section. A point with maximum intensity in the slice is projected on each point in the image. For details on how to set the thickness, see the next section.
The MinIP mode . Similar to the previous mode, but points with minimum intensity are projected on the image.
The AIP mode. Similar to the previous mode, but the intensity of each point equals the average intensity of the points projected on this point in the image.
This tool is also available from the MPR main menu item.
In the MIP, MinIP and AIP render modes, the slice thickness is set using the Thickness button on the toolbar. Click the button and select the predefined values from the list, or click the User defined button to specify your own value. In the projection window, the slice borders are marked by lines (the red arrows in Fig. 5.24).
To set the thickness of solely the slice which is projected on a sertain plane, move the cursor to any line, marked by the arrows in Fig. 5.24, for the corresponding slice and move it, holding the left mouse button.
Setting the thickness is also available from the MPR main menu item.
