Acquisitioning (Scanning)
6-9
If the Horizontal & Vertical skull position looks correct, then
proceed to the
Volume scan. Otherwise, re-position the Patient or
the volume center to achieve better positioning and restart this
procedure. To ensure good quality, the required image should appear
within a ¼ inch border of the Preview screen.
3. Dry Run is used to demonstrate the motion of the machine to the
Patient, without exposing, as well as to check for shoulder
clearance. The Dry Run scan performs half the revolution and
resets immediately. If desired, do a Dry Run by clicking the
Dry
Run button.
NOTE:
It is critical that the Patient is instructed to hold still, swallow
before the scan, take shallow breaths during the scan and may want
to close his/her eyes so he/she won’t be tempted to follow the turret
with their eyes during the scan.
WARNING
The X-ray unit may be dangerous to the Patient and operator if you
do not observe and follow the safe exposure factors and operating
instructions. Do not operate this system unless you have received
training to perform a procedure.
4. Click Capture to start the acquisition.
5. Ensure that nobody is in the operator area or Patient area.
6. Click OK to start the exposure.
The turret rotates around the Patient’s head. The exposure buzzer
sounds for the duration of that rotation, although the true exposure
time is much less because the exposure pulses on and off.
The progress of the scan is displayed on the Progress bar at the
bottom of the Acquire window.
