Title:
PARTICLE BEAM MONITORING DEVICE, PARTICLE BEAM THERAPY SYSTEM AND PARTICLE BEAM MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/038941
Kind Code:
A1
Abstract:
The purpose of the present invention is to enhance measurement sensitivity and measurement resolution when taking a measurement at the position at which a charged particle beam is applied. In the present invention, a particle beam monitoring device (1) is provided with: a sensor (14) for detecting radiation generated by the interaction between a charged particle beam (52) and a patient (50) serving as the object of measurement; and a shield body (12) for limiting the detection range of the sensor (14). The shield body (12) has a greater shielding effect on the radiation on the upstream side of the trajectory of the charged particle beam (52) than on the downstream side thereof, when viewed from the sensor (14).
