Abstract
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.
