Starting Irradiation
Note: Screen representations throughout this chapter and throughout this part may
show ‘Control Mode: EMR-Centric’ or ‘Control Mode: DEV-Centric’ at the bottom.
When working in Standalone mode, you will notice that the mode indication reads
‘Stand-Alone’.
Process
Before starting the irradiation you must reset the DCEU (refer to Chapter 15,
“Resetting a Dose Counter Electronic Unit”).
During irradiation, the movement of any Patient Positioning Device (PPD) is
prevented and power to the drive is interrupted.
Important Make sure there is not too much noise/vibrations in the treatment room
during irradiation.
A high level of vibrations or sounds can cause inappropriate counting
of MU to the DCEU.
Important As a Radiation Therapy Technologist (RTT), make sure to visually
inspect that the accessory (accessories) is (are) correctly in place when
required for the current treatment (i.e., correctly inserted and not semi-
inserted, in the correct orientation, etc.), as required by the procedure
established by the administration of your center.
