Radiation dosimetry apparatus and method, and dosimeter for use therein
摘要：
In order to overcome or at least mitigate difficulties in compensating for movement of the target, for example a tumour during radiotherapy, a dosimetry apparatus and method embodying the present invention employ a dosimeter having at least one radiation detector and at least one magnetic position sensor located a predetermined distance apart. Radiation level readings from the radiation detector and position readings from the position sensor are monitored and correlated, conveniently according to time, to obtain the position of the radiation detector when a particular radiation level was detected.
摘要（中）：

为了克服或至少减轻补偿靶的运动的困难，例如放射治疗期间的肿瘤，体现本发明的剂量测定装置和方法采用具有至少一个辐射检测器和至少一个磁性位置传感器的剂量计 相隔预定距离。 从位置传感器的辐射水平读数和来自位置传感器的位置读数可以方便地根据时间进行监测和相关，以便在检测到特定辐射水平时获得辐射探测器的位置。
