Operation
Move the trackball to scroll CT/MR
image.
See also Chapter 5.16.10
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. See also Chapter 5.16.10 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 5.16.9 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 5.16.9 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:
a) Tap [Fine Tuning] on the touch screen. Press <Freeze> to freeze the image.
 Unfreeze the ultrasound image (tapping [Freeze US] to dim the soft key);
For CT/MR image is frozen, whereas the ultrasound image is not, take CT/MR image
as the comparison reference (keeping CT/MR image still); tune the probe scan
orientation and position to obtain the ultrasonic plane which is identical with that on
the CT/MR image (the ultrasonic plane moved).
 Or, unfreeze the CT/MR image (tapping [Freeze MPR] to dim the soft key);
For the ultrasound image is frozen, whereas the CT/MR image is not, take the
ultrasound image as the comparison reference (keeping ultrasonic plane still); tune
