QA BEAMCHECKER™ PLUS 62
For efficiency, it is recommended that the dose is kept at a conventional fraction size to
shorten delivery time.
NOTE: When planning delivery, limiting dose to the chambers when the gantry is at 90° and
270° (± 10-15°) is recommended. The parallel plate geometry of the chambers may produce
inconsistent results when delivery is provided parallel to the chamber surface.
Refer to the appropriate Treatment Planning and Treatment Delivery System documentation
from Accuray for specific information on developing treatment plans of this variety.
13.4 Dynamic 5 Channel Planning
A plan or plans can be created using the treatment planning software for the treatment
system used. Ideally, the plan developed challenges the system in reproducibility, thereby
potentially identifying any delivery issues in the QA routine. A different dose prescribed to the
each of the chambers is a one possible technique.
For efficiency, it is recommended that the dose is kept at a conventional fraction size to
shorten delivery time.
NOTE: When planning delivery, limiting dose to the chambers when the gantry is at 90° and
270° (± 10-15°) is recommended. The parallel plate geometry of the chambers may produce
