Title:
PARTICLE BEAM THERAPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207244
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a particle beam therapy device provided with a beam adjustment device that supports the adjustment of a beam axis. This particle beam therapy device (100) is provided with a beam adjustment device (18) that supports the adjustment of a beam axis, which is an axis in the propagation direction of a charged particle beam (44) when the charged particle beam is not scanned by scanning electromagnets (25x, 25y), in a particle beam irradiation device (4). The beam adjustment device (18) is provided with a beam adjustment calculator (17) which calculates the values of excitation currents of two x-direction steering electromagnets (23a, 23c) and two y-direction steering electromagnets (23b, 23d) so that the beam position of the charged particle beam (44) on a first screen monitor (30), disposed to be movable in a direction crossing the beam axis at the downstream side of the scanning electromagnets (25x, 25y), and on a second screen monitor (31), disposed detachably on a tip part (snort (39)) of the particle beam irradiation device (4), is present on a reference beam trajectory (45) passing through an isocenter (48).
