Aligning a Patient in the GTR
Positioning and aligning a patient in the GTR involves the operations that follow.
WARNING In a gantry treatment room equipped with a gantry rolling floor, patient
loading should only be performed with the nozzle positioned in the
upper part of the gantry, between 90° and 270°.
WARNING As a Radiation Therapy Technologist (RTT) you should perform motion
with the patient on the support (i.e., couch or chair) only after the
patient has been securely immobilized on the support.
CAUTION When installing the patient onto the couch, do respect the maximum
weight allowed by the Patient Positioning system (PPS). Exceeding the
allowed values will jeopardize result precision. For details on the
allowed weights, refer to section Allowed Maximum Weight on the
Couch in Chapter 7.
