Abstract:
1. A method of irradiating a target tissue in a patient, which method comprises: positioning the patient on a patient support system so that the target tissue in the patient is within irradiating distance of multiple beams of radiation, wherein (a) each beam, which is from a different source or a single arcing source, is from a different direction and has a central axis, (b) the central axes of the multiple beams are focused on a fixed point in the target tissue, and (c) each beam rotates around its own central axis and around the fixed point of focus, and continuously moving the patient support system relative to the fixed point of focus of the multiple beams of radiation and, coordinately with movement of the patient support system, continuously rotating at least one beam of radiation around the fixed point of focus in the target tissue, which comprises and/or is adjacent to a non-target tissue, so that the fixed point of focus is constantly moving within the target tissue, while simultaneously and/or sequentially irradiating the target tissue, whereupon the target tissue in the patient is irradiated in a pattern created by the coordinated continuous movement of the patient support system and the continuous rotation of at least one beam of radiation around the fixed point of focus in the target tissue.
