The effects of random (drifting) errors in actual seed placement during prostate implants have been evaluated by using geometrically optimized implants of I-125 and Pd-103 seeds. Results indicate that small random deviations in the seeds placement from the preplant position may affect the planned dose and beam profiles significantly.
通过使用 I - 125 和 Pd - 103 种子的几何优化植入物,对前列腺植入过程中实际种子放置的随机(漂移)误差的影响进行了评估。结果表明,种子放置相对于种植前位置的小随机偏差可能会显著影响计划剂量和射束轮廓。
