摘要:
Disclosed is a safety system of a radiation therapy apparatus capable of verifying accuracy and reproducibility. The safety system of the radiation treatment apparatus capable of verifying accuracy and reproducibility according to the present invention is used in three dimensional conformal radiation therapy, radiosurgery or stereotactic radiosurgery and provided with a driving unit moving around a physical body of a patient and a radiation generator installed in the driving unit. The safety system comprises: a laser distance detection sensor installed on an external side of the driving unit facing the patient and detecting a distance to the patient in real time to generate information on a therapy distance; and a control unit comparing the information on the therapy distance received from the laser distance detection sensor with each other or comparing the information on the therapy distance received from the laser distance detection sensor with information on a preset distance to generate a difference value and controlling operation of the radiation generator according to the difference value in real time. The present invention measures and analyzes the distance in real time through the laser distance detection sensor even when the patient unexpectedly moves during radiation therapy to safely control the radiation therapy apparatus, is capable of verifying the accuracy of the radiation therapy in the case that difference between planned therapy and real therapy occurs and is capable of verifying the reproducibility when the radiation therapy is repeated.정확성 및 재현성을 확인할 수 있는 방사선 치료장치의 안전시스템이 개시된다. 본 발명의 정확성 및 재현성을 확인할 수 있는 방사선 치료장치의 안전시스템은, 3차원 입체조형치료, 방사선 수술 또는 정위적 방사선 치료에 사용되고, 환자의 신체 주변에서 움직이는 구동부 및 구동부에 장착되는 방사선 발생장치가 구비되는 방사선 치료장치의 안전시스템에 있어서, 환자를 향하는 구동부의 외측면 상에 설치되어 환자와의 거리를 실시간으로 감지하여 치료거리정보를 생성하는 레이저거리감지센서; 및 레이저거리감지센서로부터 수신된 치료거리정보를 서로 비교하거나 레이저거리감지센서로부터 수신된 치료거리정보와 기설정된 사전거리정보를 비교하여 차이값을 산출하고, 차이값에 따라 방사선 발생장치의 작동을 실시간으로 제어하는 제어부를 포함하는 것을 특징으로 한다. 본 발명에 의
