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.

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

A boron neutron capture therapy device compatible with a rotating target and a fixed target and a target replacement method are provided, including a beam shaping body and a vacuum pipeline, where the beam shaping body includes a base platform, two sides of the base platform are each provided with a reflector module and a back reflector, and a compatible cavity capable of accommodating a rotating target module is disposed on the base platform; when the rotating target is adopted, the rotating target module is mounted in the compatible cavity, and the vacuum pipeline is connected with the rotating target module; and when the fixed target is adopted, the fixed target is detachably mounted on the vacuum pipeline. The boron neutron capture therapy device can meet the arrangement requirements of the fixed target and the rotating target at the same time, which is convenient for adjustment and updating of apparatuses.

Boron neutron capture therapy device compatible with rotating target and fixed target and target replacement method

A boron neutron capture therapy system includes a beam shaping body with a proton channel and a replaceable target assembly slidably disposed inside the proton channel, where a current monitoring apparatus is disposed outside the beam shaping body, the target assembly is provided with a moving contact, and the current monitoring apparatus is provided with a stationary contact forming a moving contact conductive mode with the moving contact. For the boron neutron capture therapy system, the current monitoring apparatus and the target assembly are connected through a moving contact conductive mode, avoiding the influence on the movement, automatic replacement, storage and the like of the target assembly caused by hard-wired connection, operations such as automatic adjustment, contact for power-on and non-contact for power-off can be performed, a target current can be measured and read in real time under full automation, the manual disconnection operation is not needed.
