Objective To monitor the performance constancy of the HS-126E automatic X-ray film processor and to investigate the effects of chemical processing time on the reproducibility of film dosimetry.

The doses of interesting points were measured using a 0 23 cc chamber and the isodose distributions of interesting planes were measured using RIT 113 film dosimetry system in the phantom.

使用023cc电离室测量出体模中感兴趣点上的吸收剂量；使用RIT113胶片剂量分析系统测量出体模中感兴趣平面上的剂量分布。

Film dosimetry is convenient to use, high special resolution, provides record of the integrated two dimensional dose distributions, never mind the lateral electronic disequilibrium in any phantom.

胶片与其他探测器相比，具有使用方便，空间分辨率高，能记录完整的二维剂量分布，还能够放置在各种模体中而不用考虑侧向电子不平衡问题等优点。
