Boron neutron capture therapy (bnct) system comprising a target current monitoring device

Abstract

A target current monitoring device for a boron neutron capture therapy system includes a beam current shaping body and a replaceable target part disposed inside a proton channel of the beam current shaping body, and further includes an automatic conduction detection device independent of the target part, where the automatic conduction detection device includes a contact part and an external current monitoring apparatus electrically connected with the contact part, the contact part is disposed on a moving path of the target part, and the contact part forms a circuit with the external current monitoring apparatus after being in contact with the target part. Since the automatic conduction detection device and target assembly are independently disposed and no hard-wired connection of electric wires exists, the current of the target can be read in real time under full automation, and the automatic replacement, movement and storage of the target can be achieved.
