Verifying Beams
Some beam parameters are validated by making measurements with a water
phantom before using a new beam. This validation ensures consistency of the
settings between the Treatment Planning System (TPS) and the PTS equipment.
The list of recommended parameters to be checked for each new beam is as follows:
Range verification of the planning beam. The range needs to be verified for each
new beam and the required range needs to be modified in the prescription if the
discrepancy with the measured range is too large.
Measurement of the absolute dose for each beam.
WARNING As a physicist using the systems (Treatment Planning System and
Proton Therapy System) it is your responsibility to validate some
parameters to check the consistency of the settings between the
Treatment Planning System and the Proton Therapy System
equipment.
