摘要
由于侧向带电粒子平衡的缺失、主光子源的遮挡,以及在小射野测量中可以选择的探测器有限,对现代放射治疗技术进行小野剂量学测定提出诸多挑战,这些挑战极大影响了剂量学的准确性.过量辐射事故表明对小野剂量学测定的适当方法了解不足.本综述介绍了目前适合在小野剂量学测量中应用的各类型探测器,包括微型电离室、半导体探测器、金刚石探测器、塑料闪烁体探测器、放射变色胶片、热释光探测器、放射光致发光玻璃探测器、光受激发光探测器、聚合物凝胶剂量计,为物理师在选择小野探测器时提供参考.
Abstract
The lack of lateral charged particle equilibrium,the obstruction of the primary photon source,and limited detectors available for small field measurements challenged the modern radiotherapy technology for small field dosimetric measurement,greatly affecting the accuracy of dosimetry.The excessive radiation accidents indicate a lack of understanding of appropriate methods for small field dosimetric measurement.Herein an overview on various types of detectors that are suitable for small field dosimetric measurement,including micro-ionization chamber,semiconductor detector,diamond detector,plastic scintillator,radiochromic film,thermoluminescent detector,radio-photoluminescent glass,optically stimulated luminescent detector,polymer gel dosimeter is provided for offering a reference for physicists in selecting small field detectors.
