Move the trackball to pan CT/MR
image.
Move the trackball to scroll CT/MR
image.
See also Chapter 5.17.10
Rotating/Scrolling CT/MR Image
for scrolling operations.
Move the trackball to view the
ultrasound cine.

Toggle <Steer> left to change the active plane of CT/MR image (sagittal plane, transverse
plane, coronal plane). Varied planes can be panned, scrolled or rotated through the axis.

Rotate CT/MR image axially (rotate the <C> knob to cycle through Z-axis). See also
Chapter 5.17.10 Rotating/Scrolling CT/MR Image for operations.

Rotate [Fusion Ratio] to adjust the display ratio that the ultrasound image registers with the
CT/MR image. The ultrasound image and CT/MR image are displayed well. See also
Chapter 5.17.9 Parameter Setting for operations.

Rotate <Zoom> on the control panel to zoom in or zoom out CT/MR image;

Rotate the knobs beneath [Offset X] and [Offset Y]. Pan the CT/MR image. See also
Chapter 5.17.9 Parameter Setting for operations.
c) Tap [Confirm Registration] to complete registering. The ultrasound image and CT/MR image
appear synchronously after the registration accomplishment.
Note:
Do not move the magnetic generator and the patient for any circumstances after the
registration accomplished. Otherwise, the registration display for CT/MR image and the
ultrasound image is affected.
9. Checking registration effect:
After completing 8
th
step (first registration), move the probe and adjust the probe scan angle and
position. View the synchronous effect of varied planes (coronal plane, sagittal plane, transverse
plane) from the ultrasound image and CT/MR image.
Synchronous display effect: The Ultrasound System represents the ultrasound image and CT/MR
image synchronously after the ultrasound image and CT/MR image are registered first time with the
magnetic spatial positioning and in the aid of positioning (probe) sensor receiving the spatial
message from the probe.
10. Fine tuning (second time registering):
If the ultrasound image and VT/MR image are not registered precisely after first-time registering,
perform the fine tuning operations below:
