Abstract

To quantitatively assess of Gating Radiotherapy (GRT) system and Dynamic Tumor Tracking Radiotherapy (DTTRT) system using MLC developed at KIRAMS (Korea Institute of Radiological & Medical Sciences) and evaluate effectiveness and efficiency of beam delivery for the both RT system. DTTRT system resulted to same treatment effect compared with the GRT system controlled with the gating rate of 20%. However, when treat by applying lower gating rate for the GRT system, longer treatment time give inconvenience to patients and cause obstacle to effective utilization of the equipment. On the one hand, DTTRT system presents advantage to reduce treatment time and to achieve effective dose delivery.
