A high-resolution radiochromic film dosimetry (Hr-RCFD) method has been applied to verify a small-field stereotactic radiosurgery (SRS) plan. This was done by exposing a RCF in a Perspex head phantom undergoing the same treatment plan as the patient. The dose distribution obtained by the Hr-RCFD was verified against that calculated by the stereotactic treatment planning system and the result was satisfactory. The Hr-RCFD method has been found to be an accurate and practical tool in verifying small-field SRS plans.
一种高分辨率放射变色薄膜剂量测定法（Hr-RCFD）已被应用于验证小视野立体定向放射外科手术（SRS）计划。这是通过在一个与患者接受相同治疗计划的有机玻璃头部体模中曝光一张放射变色薄膜（RCF）来实现的。将通过Hr-RCFD获得的剂量分布与立体定向治疗计划系统计算出的剂量分布进行比对，结果令人满意。已发现Hr-RCFD方法是验证小视野SRS计划的一种准确且实用的工具。
