Abstract

We have developed the prototype Multi-leaf Collimator(MLC) for medical linear acclerator. In this study, we have examined the clinical effectiveness of our newly developed MLC by analysing treatment pattern of radiation therapy and studied the radiation safety by measuring the transmitted radiation and the leakage radiation. Over 81% patients can be treated with new MLC(20 pairs of leaves) and 98% with 30 pairs of leafed-MLC, while 95% with commercial MLC. New MLC showed superior properties of radiation leakage and transmission to commercially available MLC.
