6 Image Acquisition
– Tap [View Type] to change the active plane of CT/MR/PET image (sagittal plane,
transverse plane, coronal plane). Varied planes can be panned, scrolled or rotated
through the axis.
– Rotate CT/MR/PET image axially (rotate the <C> knob to cycle through Z-axis). See
XX for operations.
– Rotate [Fusion Ratio] to adjust the display ratio that the ultrasound image registers
with the CT/MR/PET image. The ultrasound image and CT/MR/PET image are
displayed well.
– Rotate <Zoom> on the control panel to zoom in or zoom out CT/MR/PET image;
– Rotate the knobs beneath [Offset X] and [Offset Y]. Pan the CT/MR/PET image.
NOTE:
• After tapping [Registration] each time, Tap [View Type]. It is convenient for panning or
scrolling CT/MR/PET image.
• Do not move the magnetic generator and the patient for any circumstances after the
registration accomplished. Otherwise, the registration display for CT/MR/PET image
and the ultrasound image is affected.
c. Tap [Confirm Registration] to complete registering. The ultrasound image and CT/MR/
PET image appear synchronously after the registration accomplishment.
9. Checking registration effect:
After completing 8th 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/PET/freehand image.
Synchronous display effect: The Ultrasound System represents the ultrasound image and CT/
MR/PET/freehand image synchronously after the ultrasound image and CT/MR/PET/freehand
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 CT/MR/PET/freehand 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> or tap [Freeze US] and [Freeze
MPR] to freeze the image.
–
Unfreeze the ultrasound image (tapping [Freeze US] to dim the soft key).
– For CT/MR/PET/freehand image is frozen, whereas the ultrasound image is not, take
CT/MR/PET/Freehand image as the comparison reference (keeping CT/MR/PET/
freehand image still); tune the probe scan orientation and position to obtain the
ultrasonic plane which is identical with that on the CT/MR/PET/freehand image (the
ultrasonic plane moved).
– Or, unfreeze the CT/MR/PET/freehand image (tapping [Freeze MPR] to dim the soft
key).
– For the ultrasound image is frozen, whereas the CT/MR/PET/freehand image is not,
take the ultrasound image as the comparison reference (keeping ultrasonic plane
still); tune the probe scan orientation and position to obtain the CT/MR/PET/
Freehand plane which is identical with that on the ultrasound image (the CT/MR/
PET/Freehand plane moved).
b. Tap [Confirm Registration] to complete the fine tuning.
