Determination of Dose Profile Data With Film Dosimetry

Abstract

Almost all external radiotherapy planning systems use dose profile data. There are various methods to measure these profiles. Direct measurements with semiconductor detectors are widely used. But this method takes lots of time especially at linear accelerators. We developed a simple method for this purpose. Dose profiles are measured with using radiographic films and verification films. Suitable modifications are done with derived sensitometric curve. Results are compared with original profiles. For the Co60, this method is found as an alterative to other methods with acceptable accuracy (% +/- 2).
