Abstract

A unit is discussed which employs a pair of matched silicon diode detectors to check the constancy of the output, beam quality, field flatness, and symmetry of teletherapy equipment. The unit has proven useful, but the long-term stability of the diode-amplifier system must be considered, because two years of experience has demonstrated significant sensitivity changes in the diodes.

摘要

本文讨论了一种装置，它使用一对匹配的硅二极管探测器来检查远距离治疗设备的输出稳定性、射束质量、射野平坦度和对称性。该装置已被证明是有用的，但必须考虑二极管 - 放大器系统的长期稳定性，因为两年的经验表明二极管的灵敏度有显著变化。
