Patent number: 9941440Abstract: One feature pertains to a radiation dosimeter comprising a microdosimeter cell array that includes a first microdosimeter cell having a first semiconductor volume configured to generate a first current in response to incident radiation. The first semiconductor volume may have at least one of a first size, a first shape, a first semiconductor type, and/or a first semiconductor doping type and concentration that is associated with a first biological cell type or a first biological cell component type. The dosimeter may further comprise a processing circuit communicatively coupled to the microdosimeter cell array and configured to generate a signal based on the first current. The signal generated may be indicative of an amount of radiation absorbed by the microdosimeter cell array. A display may be utilized by the dosimeter to show a radiation level reading based on the signal generated.Type: GrantFiled: August 26, 2015Date of Patent: April 10, 2018Inventors: James Francis Ziegler, Chao-tuan Liu, Razmig Messerian, Wayne Newhauser

Patent number: 7405407Abstract: A therapy system using an ion beam, which can shorten the time required for positioning a couch (patient). The therapy system using the ion beam comprises a rotating gantry provided with an ion beam delivery unit including an X-ray tube. An X-ray detecting device having a plurality of X-ray detectors can be moved in the direction of a rotation axis of the rotating gantry. A couch on which a patient is lying is moved until a tumor substantially reaches an extension of an ion beam path in the irradiating unit. The X-ray tube is positioned on the ion beam path and the X-ray detecting device is positioned on the extension of the ion beam path. With rotation of the rotating gantry, both the X-ray tube emitting an X-ray and the X-ray detecting device revolve around the patient. The X-ray is emitted to the patient and detected by the X-ray detectors after penetrating the patient. Tomographic information of the patient is formed based on signals outputted from the X-ray detectors.Type: GrantFiled: February 9, 2007Date of Patent: July 29, 2008Assignees: Hitachi, Ltd., Board of Regents, The University of Texas SystemInventors: Kazuo Hiramoto, Hiroshi Akiyama, Yoshihiko Nagamine, Alfred Smith, Wayne Newhauser
