摘要： The invention is related to particle induced radiography system, comprising a particle radiation source device, implant module, external detector device, central module and other controls, in which the implant module comprises active and/or passive components in tandem with the readout electronics and communication chosen to measure the beam properties and to generate and detect secondary gamma photons from the nuclear interactions, the external detector device provides a position sensitive gamma detector with a high detection efficiency, good spatial resolution and a relatively large field of view necessary for particle treatments useful in monitoring both the implanted device and the patient anatomical areas under treatment, and the external detector device can also be used to perform 3D spectral imaging on any material samples using proton beam as a probe.
