
ROI size and position
Roll the trackball to change the ROI size and position. Press the <Set> key to toggle between
setting the size (dotted line) and position (solid line).

Curved VOI adjustment
Roll the trackball to change the curved VOI position. Press the <Set> key to switch between
the changing ROI and curved VOI states.
This function changes the curved shape of the nearest VOI section and facilitates observation
of the volume data of interest.
When a triangle of control point is displayed on the curved VOI, it can be adjusted both in
acquisition preparation status, and in the A, B and C sections of review/4D imaging status.
The orientation and shape (line or dot) of curved VOI vary depending on the view direction:
View Curved VOI
U/D At the upper part of curved VOI
D/U At the lower part of curved VOI
L/R At the left part of curved VOI
R/L At the right part of curved VOI
F/B Displays as a dot
B/F Displays as a dot

MPR
The principle of 3D imaging is to render a 3D image from multiple 2D image information. The
following describes the spatial relationship of 3 MPRs (A, B and C) and the 3D image (VR).
In the quad display format view, the screen displays 3 MPRs (A, B and C) and the 3D image.
