Abstract :
The purpose of this study is to investigate the accuracy of dose predicted by cone convolution algorithm. This work describes an experimental verification of two dose calculation algorithms available on the Philips Pinnacle3 (version 8.0) commercial radiotherapy treatment planning system (TPS): Collapsed cone convolution and Fast convolve. Both experiment and TPS were tested for 6 MV photon beam, the fields were 5cm×5cm and 10cm×10cm respectively. Dosimetry was performed with thermoluminescent dosimeters. At the end of this article, we analyzed the difference between calculation and experiment.
