Dosimetric Verification of Collapsed Cone Convolution Algorithm in Heterogeneous Media
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
This article in view of the Hainan Provincial People’s Hospital clinical data conformity work actual situation, proposed a set based on the DOP technology clinical data conformity and the synthesis information retrieval plan, with emphasis discussed the difficulty, DOP platform technical aspect and so on superiority and characteristic, system realization goal, technical construction and design main point which the data conformity work faces questions, by achievement to large-scale general hospital clinical information system data conformity preliminary discussion.
