The complexity of modern radiotherapy requires a comprehensive quality assurance programme, including in vivo dosimetry. In this paper, the use of the detector systems most often used for in vivo dosimetry [diodes, thermoluminescence detectors, metal oxide field effect transistors and electronic portal imaging devices (EPIDs)] will be summarised. Although point detectors are useful for the verification of conventional 3-D conformal radiotherapy, the use of 2-D detector systems, such as EPIDs, is required for the verification of more complicated techniques, including intensity-modulated radiotherapy.
现代放射治疗的复杂性需要一个全面的质量保证计划，包括体内剂量测定。本文将总结最常用于体内剂量测定的探测器系统（二极管、热释光探测器、金属氧化物场效应晶体管和电子射野影像装置）的使用情况。尽管点探测器对于传统三维适形放射治疗的验证很有用，但对于包括调强放射治疗在内的更复杂技术的验证，需要使用二维探测器系统，如电子射野影像装置。
