Abstract: A work holding mechanism includes a body part having a three-dimensional shape including at least a recess or a protrusion, and an adsorption part for holding a work by adsorbing the work onto the body part in conformity to the three-dimensional shape of the recess or the protrusion provided in the body part. The work is held by being adsorbed in conformity to the three-dimensional shape of the body part, and, therefore, the amount of usage of the work in a work molding system can be reduced as compared with when the work is held so as to have a flat shape.

Abstract: A particle beam irradiation system includes a particle beam irradiation apparatus, which is free of a gantry structure, having a particle beam irradiator for irradiating an affected area of a patient with a particle beam, the particle beam irradiator being housed in a chamber, a CT scanner installed in the chamber, for positionally confirming the affected area of the patient, a drive unit for moving the patient from a detection range to an irradiation range, a patient fixing device for fixing the patient in position, the device being mounted on the drive unit for rotation, and a housing unit having a structure housing the drive unit with the patient fixing device mounted and the CT scanner, the housing unit being rotatable about an axis perpendicular to a plane including a direction in which the particle beam is applied and a direction in which the drive unit moves.

Abstract: A composite system for radiation therapy includes a CT scanner for checking the position of an affected portion of a patient to be irradiated, an irradiation apparatus for disposing, on the basis of positional information of the affected portion checked by the CT scanner, the patient at a specific position at which the affected portion is aligned to an irradiation position, and performing irradiation to the affected portion, a common bed used for the CT scanner and the irradiation apparatus, in a state that the patient lies on the common bed and moving means for moving the patient from the CT scanner to the specific position of the irradiation apparatus.

Abstract: A radiotherapeutic aid assembly for forming a radiotherapeutic aid for use in at least one of applications including marking an irradiation location in breast radiotherapy, fixing a patient, and assisting in stabilizing the shape of an affected part, comprises a first strip shell member, a second strip shell member, and a third strip shell member. The first through third strip shell members can be shaped along a body surface of the patient in surrounding relation to an irradiation area on the body surface.

Abstract: A synchronized moving radiation shield apparatus includes at least one shielding block disposed under a radiation pathway of a radiation therapy unit in such a manner that a radiation field is formed with the shielding block, wherein an affected portion of a person is exposed to radiation through the radiation field while radiation therapy of a portion, other than the affected portion, of the person, is shielded by the shielding block. The apparatus further includes a movable portion for movably holding the shielding block while not blocking the passing of radiation through the radiation field; drive means, connected to the movable portion, for moving the radiation field to a specific position; and control means for controlling the drive means in such a manner that the radiation field is movable in matching to a variation in position of the affected portion.
