고 에너지 방사선치료 시 GEANT4-DICOM과 TPS간 선량비교 연구

A Comparative Study on the Dose of GEANT4-DICOM to TPS for High-Energy Radiation Treatment

Radiation therapy is one of the beneficial choices in the treatment of cancer. This is a comparison of TPS(Treatment Planning System) and GEANT4-DICOM, which should be preceded by the best radiation therapy. A treatment plan for prostate cancer was established with Eclipse and the point doses 366.1 cGy, 189.1 cGy, 213.4 cGy, 127 cGy, 105.7 cGy of any five prostate, bladder, rectum, right femoral head and left femoral head were identified. GEANT4-DICOM simulation showed that the results of Eclipse and ± 2% dose error were confirmed. The monthly X-ray output agreement management value recommended by TG-142 is ± 2%, which means that the experimental results can be meaningful. In conclusion, GEANT4-DICOM is an infinite way to obtain more extended dose information once the time constraints are overcome in the simulation.
