5.8.1. Pre-3D/Pre-4D

The Pre-3D and Pre-4D mode supports defining the 3D and 4D acquisition location and settings.
Figure 5-2 shows an example of the pre-3D image. The VOI (Volume of Interest) indicates the
portion of the image that will be used for 3D. The top horizontal line is the clip plane. The initial
volume rendering will show everything below this line. It can be adjusted to a curved line
upwards and downwards and its top point can be adjusted to left or right by using the trackpad.
Also the position/size of the VOI can be adjusted by using the trackpad. Press Set key to toggle
among VOI position, VOI size and horizontal line adjusting.
