Cancer patients are continuously increasing in Korea and chemotherapy using radiotherapy equipment is increasing. 50% of cancer patients in advanced countries are receiving radiotherapy and about 30% of cancer patients in Korea are receiving radiotherapy currently. 

In Korea, radiotherapy equipment is a medical device that is regulated by medical device legislative system and at the same time as a radiation emitting device it is regulated by nuclear safety law. Radiotherapy using radiotherapy equipment is regulated by nuclear safety law but patient safety-centered management system for radiotherapy equipment is needed. 

The purpose of this study is to investigate domestic current status on radiotherapy equipment control and to examine relevant management system and recommendations of foreign countries in perspective of healthcare technology, which could supply evidence for preparation of patient-centered safety management system to improve quality assurance of radiotherapy and radiotherapy equipment.
