Radiation Therapy Quality Control System

A good quality control system should tell you if there is a mistake and not depend upon your search to find one.

The dose to the patient is reconstructed from integrated images of the delivered treatment beams.

Which is more meaningfull to review and compare, the dose to a phantom, or the dose to the patient?

This system works with the input from the Varian EPID in integration mode. See the Varian Example below.
