Patent number: 7346144Abstract: A system and method for delivering radiation to an object. A computer tomography machine generates CT data of the object. A radiation source with an output beam is directed to a predetermined irradiation field of the object. A detector above the object controls the output beam to the predetermined irradiation field of the object. A processor calculates the dose to the predetermined irradiation field of the object. Another detector below the object which measures the radiation delivered to the object.Type: GrantFiled: March 14, 2002Date of Patent: March 18, 2008Assignee: Siemens Medical Solutions USA, Inc.Inventors: John H.

Patent number: 5724403Abstract: In a radiation emitting device, particularly in a radiation treatment device (2), the actual radiation delivered to an object (13) via a radiation beam (1) is adjusted to match the field to be irradiated on object (13). Jaws (250, 252, 254, 256) are arranged between a radiation source and an object (13) to provide an opening (110). The field is divided up into sections, and wedge corrections and/or monotonic functions are calculated for each of the sections. The wedge corrections and/or monotonic functions are used to deliver radiation to each of the sections in the field. Jaws (250, 252, 254, 256) and the radiation dose are controlled during the treatment of each of the sections.Type: GrantFiled: June 28, 1996Date of Patent: March 3, 1998Assignee: Siemens Medical Systems, Inc.Inventors: Ramon Alfredo Carvalho Siochi, Francisco Miguel Hernandez-Guerra
