7 3D/4D
Operator’s Manual 7 - 35
Rotate A, B or C plane respectively.
To ensure the correctness of the result, please make sure the cerebral midline on the anatomical
plane is displayed clearly and ROI enclose the whole cranial region.
5. Tap [Accept] to accept the edit to the MSP. The system recalculates the TCP, TTP and TVP
according to MSP’s position. The position and the angle for TCP, TTP and TVP appear on
MSP plane.
6. Tap [TCP]/[TTP]/[TVP] to select the plane, and rotate <M>, <PW> or <C> knob to rotate the
image plane along with X/Y/Z axis. The angle value appears on the right of the image.
7. Rotate the reference line on the MSP plane.
a. Press <Cursor> to show the cursor. Move the cursor over the red line of the MSP plane.
Press left <Set> to select the red reference line after the cursor becomes hand-shaped.
Then, the red reference line becomes dotted line.
b. Move the trackball left or downwards. The reference line rotates anticlockwise along the
center. TCP image rotates clockwise along the Y-axis, and the value of Y-axis becomes
bigger.
c. Move the trackball right or downwards. The reference line rotates clockwise along the
center. TCP image rotates anticlockwise along the Y-axis, and the value of Y-axis
becomes smaller.
d. The operations to green reference line and blue reference line are the same. TTP rotates
along Y-axis when green reference line rotating. TVP rotates along Y-axis when blue
reference line rotating.
8. Tap [Auto Measure] to show the caliper and the measurement number. The measurement
results appear on the right of the screen.
NOTE:
• There are 6 measurements:
TCP supports the measurements on TCD, cerebral fossa pool.
TTP supports the measurements on BPD, OFD, HC.
TVP plane supports the measurement on LVW.
