Abstract: A patient positioning method constituted of: rotating a pelvis support member about a first axis; rotating the pelvis support member about a second axis, between a first position where the pelvis of a patient is supported by a first face of the pelvis support member and a second position where the pelvis of the patient is supported by a second face of the pelvis support member, the rotation being at least 180 degrees about the second rotation axis; and adjusting an angle between the pelvis support member and a torso support member between a first angle where the torso support member supports the torso of the patient when the pelvis is supported by the first face of the pelvis support member and a second angle where the torso support member supports the torso of the patient when the pelvis is supported by the second face of the pelvis support member.
