in Standalone Mode Pausing and Stopping an Irradiation
|
The PTS terminates the field irradiation and archives the received parameters.
WARNING As a Radiation Therapy Technologist (RTT), when the treatment is
interrupted (e.g., the treatment is stopped after a pause, the software
crashes, etc.), you have to manually record the value reported by the
hardware Monitor Unit (MU) counter, which is located on the front
panel of the Dose Counter Electronic Unit (DCEU).
If applicable, i.e., in the Single Scattering, Double Scattering, and
Uniform Scanning treatment modes ONLY, a correction shall manually
be applied to this value to take into account the dose correction
parameters encoded in the Dosimetry Manager (ambient temperature,
atmospheric pressure, and dose correction factor).
Check that the value reported by the hardware MU counter (after
correction) matches the delivered MU value recorded in the Oncology
Information System (OIS) for this irradiation.
When the irradiation is resumed, if the system (Oncology Information
System or Proton Therapy System) proposes a MU value for the
delivered dose (MUd), you shall verify that this value matches the value
reported by the hardware MU counter (after correction), within the
foreseen precision. If the values are not in agreement, you shall use the
value reported by the hardware MU counter (after correction).
CAUTION When irradiation has terminated, provide any type of assistance that
may be required by the patient before leading the patient away from
the couch and the treatment room.
