Setting up for Portal View X-ray Images in a GTR
This procedure is for the retractable X-ray tube inside the nozzle and the associated
flat panel holder system.
To set up the equipment for the acquisition of portal view X-ray images, proceed as
follows using the wireless hand-pendant or the remote positioning controls:
Note: For further information on how to use the wireless hand-pendant, refer to
Chapter 9. For further information on how to use the remote positioning controls,
refer to Chapter 11.
1. Move the patient positioning devices to the Treatment target position.
2. Choose the adequate imaging devices setup and move them to the chosen
position.
The IN (or OUT) status of the DID panels and X-ray tube A appears on the flat
panel monitors when the selected device(s) reach(es) the desired position;
depending on the device, these positions are:
 X-ray tube: in the beam path
 DID A: its inserted (extended) position
The background becomes highlighted if the setting is not compatible with the
irradiation.
Note: The desired DID flat panel must be in place before attempting to acquire an
X-ray image.
3. The system is now ready for X-ray images to be taken.
WARNING Make sure that the DID flat panel arms are fully retracted before
attempting to move Patient Positioning Devices (PPDs) that can collide
with the flat panels.
CAUTION No Digital Imaging Device (DID) flat panel must be plugged or
unplugged from the associated power supply while the power supply
is powered on. If there is a need to connect or disconnect a DID panel,
the associated power supply must be switched off first. Else the DID
panel may suffer severe damage.
