The ultimate check of the actual dose delivered to a patient in radiotherapy can only be achieved by using in vivo dosimetry. This work reports a pilot study to test the applicability of a thermoluminescent dosimetric system for performing in vivo entrance dose measurements in external photon beam radiotherapy. The measurements demonstrated the value of thermoluminescent dosimetry as a treatment verification method and its applicability as a part of a quality assurance program in radiotherapy.
在放射治疗中，对给予患者的实际剂量进行最终检查只能通过体内剂量测定来实现。这项工作报告了一项初步研究，以测试热释光剂量测定系统在体外光子束放射治疗中进行体内入射剂量测量的适用性。测量结果证明了热释光剂量测定作为一种治疗验证方法的价值及其作为放射治疗质量保证计划一部分的适用性。
