Due to non-uniform artifacts such as beam hardening, scatter, and volume averaging, the ideal reference phantom should be as close to the target tissue as possible.
由于非均匀文物如束硬化，分散，体积平均的理想参考幻像应接近目标组织的。
Methods Using a homogeneity water equivalent rectangular phantom, the dose gradients at the interface of target volume and normal tissue was evaluated under different scatter radii.
方法采用均质水等效矩形体模，在不同散射半径条件下观察靶区和正常组织界面上的剂量梯度随散射半径的变化。
Objective Through analyzing the precision accuracy of target positions in Simulator Head Phantom to determine, the main factors influence the precision accuracy of target positions of SRS 200 X-knife. A account scale of the precision accuracy is offered for physicians and physics for reference.
目的通过分析人头模和实际患者靶点位置的精确度，确定影响SRS200X－刀系统靶点位置精确度的主要因素，给出精确度的一个数量级，供X－刀临床医师和物理师参考和借鉴。
