Initial Condition - GE VOLUSON 730Pro Basic User Manual

I mportant note: The terms "front, left, top" etc., are not orientated to the patient, but serve for
explanation. Of course, the "patient" could possibly be rotated to achieve the
position described.
By parallel movement of the reference image the new intersection lines will be displayed with the non-
reference images. The sectional planes of the non-reference images are not altered.
Axis positioning of the center of rotation in the reference image:
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.
IMPORTANT: -

System feature:
The center of rotation can not leave the display field A, B or C. In case an intersection line reaches the
field 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.

Initial Condition

Pressing the [Init] key on the control panel resets the rotations and translations of a
volume section to the initial (start) position. This key is automatically illuminated after
a volume acquisition. The center of rotations lie in the middle of the central ultrasound
line (in the middle of the scanned volume body, respectively).

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 [Par. shift] rotary control together with the
reference selection for the performance of parallel sections. In this mode only
one image is concerned by changes, leading to a higher image transfer rate.
Performing parallel sections is simple and easy to understand and therefore
should be preferred for a detail exploration of an object.
