WARNING When all alignment corrections have been applied and recorded by the
user, make sure that, according to treatment center procedures, a
second Radiation Therapy Technologist (RTT) verifies the entered
corrections.
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.
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.
WARNING The Radiation Therapy Technologist (RTT) can only press the Motion
Enable Button when the patient is safely secured on the couch or
outside the moving equipment’s operating range.
Releasing the motion enable button on the hand pendant stops the
Patient Positioning System (PPS) motion abruptly and can cause the
patient to move if not properly secured.
Important The Patient Positioning System (PPS) and the gantry rotation are
connected to emergency power in order to allow patient unloading in
case the main power supply fails.
