Abstract

The purpose of this project was to develop an effective and time-efficient plan checkingprocedure using a combination of ionization chambers and film. A 0.6 cc volume thimble ionization chamber, Kodak X-Omat V (XV) film and Kodak Extended Dose Range (EDR2) film were used. Three IMRT plans (one prostate, one head & neck and one brain) were validated. The plans were transferred from the patient geometry to a 30 cm x 30 cm x 20 cm solid water phantom. The ionization chamber was calibrated and used to measure dose delivered to the phantom. The XV film was used to compare planar dose distributions and the EDR2 film was used to compare axial dose distributions to the distributions computed by the treatment planning system. The tests set forth in this procedure provide adequate evaluation of IMRT treatment plans.
