Expected Results
M-MODE rotary control: Rotation about X-axis of the reference image.
PD-MODE rotary control: Rotation about the Y-axis of the reference image.
PW-MODE rotary control: Rotation about the Z-axis of the reference image.
C-MODE rotary control: Movement along Z-axis of the reference image.
TRACKBALL: Movement along X- and Y-axis of the reference image.
Parts of the orthogonal sections A, B and C are complied to a 3D-section aspect.
The aspect shows quasi a spatial cut into the reference image.
To select the Reference image among A, B or C.
Resets the rotations and translations of a volume section to the initial (start) position.
To change the image orientation of the 3D-image as well as the sectional planes.
The 3D-image as well as the sectional planes can be varied by their aspect ratio.
To adjust the mix ratio between two calculated modes.
