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.
WARNING As a Radiation Therapy Technologist (RTT) it is your responsibility to
verify the appropriateness of the corrections generated by the Patient
Position Verification System (PPVS).
WARNING After applying and implementing the corrections calculated by the
Patient Position Verification System (PPVS) software (e.g.,
adaPTinsight), it is recommended to take a new set of X-ray images to
verify proper positioning of the patient.
Important The same clinical devices must be put on the Patient Positioning
System (PPS) for every treatment day in order to maintain a constant
weight on the couch.
