4. Dry Run is used to give the Patient a demonstrate of the
machine motion and also checks shoulder clearance without any
radiation exposure. The Dry Run scan rotates the turret in the
exact manner that is required for the selected protocol, but does
not expose the Patient to any radiation. 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.
The X-ray device may be dangerous to the Patient and operator if
you do not observe and follow the operating instructions. Do not
operate this system unless you have received training to perform a
procedure.
5. Click Capture to start the acquisition.
6. Ensure no one is in the immediate area, then click OK.
7. Press the Scan button on the Control Box when prompted to
continue the scan process. An audible alarm is sounded and the
X-ray ON light is illuminated during radiation 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.
Once the acquisition is complete, the machine rewinds. Wait until
the machine rewinds before releasing the Patient from the
machine.
The software immediately begins reconstruction of the image data.
The time required to reconstruct depends on the acquisition scan
time and voxel size that was selected.
