A particle radiation therapy apparatusincludes: a bedfor positioning of a patient; irradiation ports() that output a particle beam in a treatment room; a horizontal-direction imaging unitcomposed of a first X-ray sourceand a first X-ray detectorthat face each other with the bedinterposed therebetween; a vertical-direction imaging unitcomposed of a second X-ray sourceand a second X-ray detectorthat face each other with the bedinterposed therebetween; a storage roomfor housing the first X-ray detectorunder the floor when the horizontal-direction imaging unitis not used; and a support memberthat moves the first X-ray detectorabove the floor and supports it between the bedand the side of the irradiation portswhen the horizontal-direction imaging unitis used.

Particle radiation therapy apparatus

A particle beam treatment apparatus includes: a rotating gantry configured to axially rotate in a state where a bed fixed to a stationary system is disposed inside the rotating gantry and an irradiation port of a beam is fixed to a body of the rotating gantry; a tunnel structure configured to have at least a horizontal floor surface and have an internal space in which at least a part of the bed is accommodated; and a rotation supporter configured to cause the tunnel structure to be stationary in the stationary system independently of axis rotation of the rotating gantry by rotationally displacing the tunnel structure with respect to an inner side surface of the rotating gantry.

Particle beam treatment apparatus

A position adjustment device for a flat panel detector comprising: a guide that is provided on a surface side of the flat panel detector and can be measured by an optical device; and a fixing member configured to fix the guide to one of a side of the flat panel detector of a position adjustment unit and a side of a support portion for supporting the flat panel detector, the position adjustment unit being provided between the flat panel detector and the support portion.

Position adjustment device for flat panel detector, position adjustment method for flat panel detector, and radiotherapy apparatus

A reactor metering pipe fixing device fixes a reactor metering pipe disposed in a reactor to a cylindrical outer surface of a jet pump diffuser and reduces stress that may be induced in a weld zone in the reactor metering pipe. An outer holding memberis held on the cylindrical outer surfaceof a jet pump diffuserby a C-shaped holding member. The reactor metering pipeis clamped from radial directions by the outer holding memberand inner holding membersand. Wedgesandare wedged into a gap between the cylindrical outer surfaceand the inner holding memberand a gap between the cylindrical outer surfaceand the inner holding memberto fix the reactor metering pipefirmly to the cylindrical outer surface
