Each of the dosimetry measurement tools has limitations that need to be considered when incorporating them into a commissioning process or a comprehensive QA program.

Witrynameans that the quality assurance QA of IMRT dose distri-butions needs to concentrate more on the cumulative deliv-ered dose rather than on the QA of individual segments, as well as checking the dose at multiple locations. The dose gradients in the IMRT dose distributions are intended to match the patient’s target and normal organ ge-ometry.

WitrynaThe QA of a 3D TPS to be used for IMRT not only consists of verifying the algorithms in the system, but is a combination of testing simultaneously the planning and delivery of IMRT.
