Abstract
A radiotherapy couch top has a frame and preferably a pair of beams extending parallel to each other, capable independently of moving towards or away from each other while keeping their mutually parallel longitudinal direction. For supporting the beams in this way, at least two linear slide bearing ways are provided, extending parallel to each other in a transverse direction perpendicular to the beams, at least one of them being supported by the frame. A pair of riding blocks are on each of these linear slide bearing ways, each supporting a corresponding one of the beams and slidable along the linear slide bearing way. Panels are placed over the beams, including one attached to the frame and another which is removable. The removable panel may be replaced with another having an open window section provided with a grid of carbon fiber stringing capable of supporting the patient and allowing projection of radiation directly onto the patient's skin.
