본 교실에서 18MeV 선형가속기를 이용한 방사선절제술에 대한 선량 측정 및 분석결과는 다음과 같았다. 1. 인체모형 팬텀을 이용한 실제 치료시 위치의 오차는 AP-LAT면과 AP-VERT면에서 0.4mm였고, AP-VERT
The stereotactic radiosurgery using ionizing radiation of high energy is a technique for exadicating intracranial small tumors, which are inaccessible or unsuitable for open surgical technique. For such a small field radiosurgery. TLD or film dosimetry is essential. The three dimensional dose planning of radiosurgery was performed with dose planning computer system (Therac 2300). The target dose distribution and its error according to patient position were discussed. And were measured of circular cone which specially designed in our Hospital. The position error of Rando Phantom compared with CT were O.4mm in the AP-LAT section and in the AP-VERT section, 1.0mm in the AP-VERT
