Patent ID: 7835492

Claim:
A medical accelerator system for image guided simultaneous treatment of all setup fields of radiation therapy and radiosurgery, comprising: a plurality of gantries having a medical accelerator and a treatment head mounted at each end of the gantry and said gantries with accelerators and treatment heads stacked as pointing at different angles and as a stationary or as a rotating device and the simultaneous beams from each treatment head at the end of the gantry is focused on to an isocentric point representing a treatment point in a patient at a distance from the treatment head; a four-beam accelerator with bending magnets to bend the beams to 90 degrees right and left and to take them away from the accelerator as a pair of right and left, top and bottom beams that connects with top and bottom octagonal beam lines; a two four-beam accelerators connected with two octagonal beam lines for a eight or sixteen treatment head medical accelerator system and for eight beam simultaneous treatment of eight treatment fields; a beam steering system consisting of 90°, 22.5°, 45° bending and focusing magnets to guide the beam traveling through the beam line and towards the target; a two four-beam accelerators connected with two octagonal beam lines and sixteen treatment heads for up to eight beam simultaneous treatments of eight fields and said treatment heads being mounted on to eight narrow gantries, one treatment head at each end of said narrow gantries and said accelerator system is placed in a gantry surrounded by a beam shield; an imaging system consisting of low energy megavoltage beam treatment heads for computerized megavoltage tomography or kilo voltage computerized tomography by attaching kilovoltage producing tubes at the free ends of the beam lines to which no accelerator heads are attached or by means of conventional portal imaging systems.
