Online OsiriX Documentation/Using 2-D thick slabs

< ^ >

OsiriX supports a 2D thick slab mode in the 2D viewer. This mode is particularly interesting if you are working with multi-slice CT. It will allow you to navigate more efficiently through a huge series.

Thick slab mode is controlled in the tool bar:

Thick Slab controller

There are actually 3 modes:
 * Mean: all slices are added and the mean is computed.
 * Maximum Intensity: maximum intensities of all pixels are extracted and displayed.
 * Minimum Intensity: minimum intensities of all pixels are extracted and displayed.

You control the number of slices with the slider. You can view the thick slab information in the lower left hand corner of the window:

Images 1 to 9 are displayed, and the total thickness is 27 mm.
