Setting up for Single-source (Rad-A) Stereoscopic X-ray
Image Acquisition in the 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 single-source (Rad-A) stereoscopic
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 PPS to the Setup or Tre a tm ent target position and use Manual
motions to pre-align the patient using the lasers.
2. Move the gantry to the Nozzle Imager Start target position.
3. Retract the snout holder into the nozzle.
4. Choose the adequate imaging devices setup and move them to the chosen
position.
WARNING Over time, the quality of digital radiographs may become degraded,
suffer from an offset or a deterioration of the gain of the flat panels or
from defective pixels.
Periodic tests must be performed to ensure sufficient X-ray image
quality. The frequency shall take into account the foreseeable flat panel
deterioration by neutrons.
In case of recalibration and corrective maintenance, contact
immediately the assigned responsible team. For detailed information
about these procedures, refer to the Original Equipment Manufacturer
(OEM) documentation.
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.
