In a treatment bed system for radiation therapy a rotation drive mechanism (relative isocentric rotation drive mechanism, rolling rotation drive mechanism, and pitching rotation drive mechanism) for rotating the bed independently around three axes (i, r, and p) perpendicular with respect to a patient each other and a parallel transfer mechanism (X-axis direction transfer mechanism, Z-axis direction transfer mechanism, and Y-axis direction transfer mechanism) for transferring the bed independently in parallel in the directions of three axes (X, Z, and Y) perpendicular with respect to a floor surface each other are provided. Thereby, the irradiation from arbitrary directions and distances to a patient held stationary on the bed can be performed.

[ What is claimed is:] [1.] A bed system for radiation therapy including a bed to hold a patient stationary when the radiation therapy treatment is performed by applying radiation irradiated from an irradiating section to a diseased part of the patient, the bed system comprising:an x-axis direction parallel transfer means for moving the bed in an x-axis direction relative to the bed;a z-axis direction parallel transfer means for moving the bed in a z-axis direction perpendicular to the x-axis direction;a y-axis direction parallel transfer means for moving the bed in a y-axis direction relative to the bed, the y-axis direction being perpendicular to the x-axis and z-axis directions;a relative isocentric rotation means for rotating the bed about an isocentric axis that designates a height direction of the patient;a rolling a rotation means for rotating the bed about a rolling axis that designates a central axis of the patient; anda pitching rotation means for rotating the bed about a pitching axis perpendicular to the central axis of the patient.
