Product Description

 

 YD—H08  γ刀头部检测模体的设计是为X、γ射线立体定向放射治疗系统质量控制的检测,完全满足WS582-2017的卫生行业标准。可测量焦点剂量率、照射野尺寸、照射野半影宽度、等中心偏差等指标。

 

整套模体由头模、体模、焦点棒三部分组成:

 

头模:直径为Φ160mm,由两个半球及连接件组成,两个半球中心可根据需要插入不同的插板,可分别插入0.015cc、0.125cc电离室,插板上带有中心探测器插孔和偏中心探测器插孔。还有插入胶片的插板。

 

体模:体模为椭圆形,椭圆柱体横断面的长轴长度为280mm,短轴长度为240mm。椭圆柱体高度为200mm。椭圆柱体上带有插槽,用于插入胶片插板和探测器插板。探测器插板上带有中心探测器插孔和偏中心探测器插孔,用于插入探测器。

 

焦点棒:用于测量机械中心与照射野中心的距离,参见《WS 582—2017 X、γ射线立体定向放射治疗系统质量控制检测规范》
