Claim Text:
1. A method for monitoring the range of a particle beam in a target, said particle beam being delivered by a radiation device, the method comprising the steps of a) providing a gamma detector configured to detect gamma quanta produced by said particle beam in said target, said gamma detector is configured to generate a detection timing signal which is correlated with a time of detection of a gamma quantum at said detector, b) providing a reference timing signal which is correlated with a time of emission of a single particle or a particle bunch from said radiation device, c) detecting gamma quanta with said gamma detector, d) determining for a number of detected gamma quanta, a time difference between the time of detection of a gamma quantum and a time of emission of the single particle or the particle bunch which has produced the gamma quantum detected, e) making a statistical distribution MDIS of the time differences obtained in the previous step, f) analyzing said statistical distribution MDIS so as to obtain information about said range of the particle beam.
