US Patent:

6422748, Jul 23, 2002

Filed:

Jun 6, 2000

Appl. No.:

09/588793

Inventors:

Joseph S. Shepherd - South Pasadena CA 91030
Robert W. Rand - Los Angeles CA 90049

International Classification:

A61N 510

US Classification:

378203, 2505051, 2505151, 378 65

Abstract:

A radiosurgery and radiotherapy system to provide diagnostic imaging and target localization via a patient 3-D mapping means such as a CT scanner or MRI, patient positioning via a four degree of freedom of motion table, and a stereotactic Cobalt 60 therapy unit incorporating multiple sources to therapeutically irradiate a target is provided. Methods of radiosurgery and radiotherapy utilizing the system are also provided. A combination of radiation source configuration, 360 degree rotational characteristics of the therapy unit, and table movement will allow any size and shape of target to be irradiated to therapeutic levels while decreasing radiation exposure to surrounding healthy tissue. A radiation beam catcher which captures greater than 80% and preferably greater than 90 percent of the radiation from the radiation sources is also provided.
