1. Display plane
2. Volume Center plane
3. Resultant image of plane within volume
4. Displacement
Reference image: A
The sectional plane migrates from the
front to the rear through the volume
body.
Reference image: B
The sectional plane migrates from the
left to the right through the volume body.
Reference image: C
The sectional plane migrates from the
top to the bottom through the volume
body
Parallel movement of the reference image will display the new intersection lines with the non-
reference images. The sectional planes of the non-reference images are not altered.
Note
The terms “front, left, top” etc., do not refer to the patient, but serve for explanation.
The center of rotation can be X/Y-positioned by the trackball. This causes also a parallel
displacement of those planes presented by the non-reference images. The intersection line of
the non-reference images with the reference image will undergo a parallel X or Y shift
accordingly.
Note
•
Positioning the center of rotation in the reference image marks that point which will not
get lost during the rotation.
•
It is recommended to use the Parellel shift touch buttontogether with the reference
selection for the performance of parallel sections. In this mode only one image is
concerned by changes.
Note
The center of rotation cannot leave the display field A, B or C. In case an intersection line
reaches the volume border, the line will stay there and the image (with further shift) will
continue to move in the shift direction. This is especially helpful when due to magnification the
display field is small compared with the area of the plane to be observed.
