According to geometrical focusing theory, the gamma knife can focus in spirals 30 beams of co - 60 gamma rays through a collimator to form a high - quality high - dose radiation field. the size of radiation filed can be varied and shaped according to tumor size for 3d radiotherapy. therefore, it can effectively increase radiation dose to tumor tissues and decease radiation dose to normal tissues
根據幾何聚焦原理,將30束鈷60伽瑪射線通過準直后經一個固定的軸線旋轉聚焦,形成品質優良的高劑量區分佈,經治療計劃系統的優化,可使高劑量區的劑量分佈,在三維方向上和腫瘤的形狀一致,從而實現三維適形放射治療。
