Abstract
A series of patients treated with large, lead protected, abdomino-pelvic fields have been investigated, to identify field placement errors. Two hundred and forty-three machine verification films were performed on a total of 33 patients, and the films analysed. Important errors were detected resulting from field rotation, lateral shift and field width variations. Suggestions are made as to how these errors may be minimised in the future.
摘要
对一系列接受大的、有铅防护的腹盆腔野照射治疗的患者进行了调查，以确定野定位误差。共对33例患者进行了243次机器验证片拍摄，并对这些片子进行了分析。检测到因野旋转、横向移位和野宽度变化导致的重要误差。针对如何在未来将这些误差最小化提出了建议。
