Active dosimetry in pulsed photon fields using photon counting pixel detectors

由于脉冲速率太高或脉冲长度太短，没有电子个人剂量计能够在脉冲辐射场中始终测量出正确的剂量或剂量率。不幸的是，脉冲辐射场通常发生在x射线检查期间。该项目的目的是开发和测试一种使用专用光子计数像素检测器的主动光子剂量测定方法，该方法能够确定连续和脉冲辐射场中的正确剂量。除个人剂量监测外，还将研究脉冲辐射场的环境剂量监测。

No electronic personal dosemeter is able to measure always the correct dose or dose rate in pulsed radiation fields of photons either because the pulse rate is too high or the pulse length is too short. Unfortunately, pulsed radiation fields commonly occur during x-ray examinations. The aim of this project is to develop and test a method for active photon dosimetry using a dedicated photon counting pixel detector that is a able to determine the correct dose in continuous and in pulsed radiation fields. In addition to personal dose monitoring, ambient dose monitoring in pulsed radiation fields will also be investigated.
