A treatment bed arranged in a tip direction of an irradiation nozzle and constructed movably, a treatment information system that manages prescription data, a treatment control system that receives a target position stored in the treatment information system to cause a main display system to display the target position, a pendant to input a movement command for the treatment bed, the main display system that receives the target position of the treatment bed from the treatment control system and displays an actual position of the treatment bed, and a patient positioning support system that calculates correction values for the target position thereof to provide the correction values to the treatment control system and the pendant are included, wherein the treatment control system sends the target position thereof to the treatment information system at a period shorter than an operation sequence thereof and stores initial values to be sent in advance.

Particle therapy system

A system update method for a particle beam therapy system, includes: a step of providing a new beam transport system in such a manner as to be branched off from an existing beam transport system of the particle beam therapy system; and a step of providing new installation connected to the new beam transport system, in which the branch is provided in a linear section of the existing beam transport system.

Particle beam therapy system and method for updating particle beam therapy system

A beam monitor system having a simple configuration for improving a measurement precision specifying a position and the width. A beam monitor system, comprising collection electrodes that include a plurality of groups each having a plurality of adjacent wire electrodes, and detect an ionized particle beam passing therethrough, a first signal processing device that sets one wire electrode in the groups of the collection electrodes as a typical wire electrode, receives a detection signal output from the typical wire electrode to process the signal and a beam monitor controller that obtains a beam position of the ionized particle beam that has passed through the wire electrodes on the basis of a processed signal from the first signal processing device.

Beam monitor system and particle beam irradiation system

Disclosed is a beam monitor system in which signals outputted from a plurality of wires are divided in a multi-wire type monitor for measuring a beam profile of a charged particle beam, an identical number of the wires are grouped, the signals of the respective groups are taken out one piece by one piece to be connected with each other, and the number of the pieces, corresponding to a number of the wires belonging to the one group, are put together to be connected to a signal processor storing connection information.
