Patent number: 10989676Abstract: A gamma-ray image acquisition device (1) acquires the direction and energy of a target scattered gamma-ray generated by Compton scattering of an incident gamma-ray and acquires the direction and energy of a recoil electron. These pieces of information are used to acquire the incident direction and energy of the incident gamma-ray. The gamma-ray image acquisition device (1) acquires a two-dimensional image by imaging spectroscopy based on the incident directions and energies of a plurality of incident gamma-rays, the two-dimensional image being an image in which each pixel corresponding to each incident direction includes energy distribution information. In the two-dimensional image, the area and the solid angle of an imaging range are proportional to each other. This enables acquiring the distribution of gamma-ray intensities without depending on distance and thereby acquiring an image that indicates more useful information than conventional images.Type: GrantFiled: May 29, 2017Date of Patent: April 27, 2021Inventors: Toru Tanimori, Atsushi Takada, Tetsuya Mizumoto, Dai Tomono

Patent number: 6822239Abstract: A particle beam image detector employing gas amplification attained by pixel-type electrodes has high sensitivity and improved reliability of electrodes. Electrons e− produced through ionization of the gas move under the force of a drift field toward a pixel in the form of a columnar anode electrode. Avalanche amplification occurs in the vicinity of the columnar anode electrode due to a strong electric field between anode and cathode and the pointed shape of the electrode. The positive ions quickly drift toward strip-shaped cathode electrodes. Electric charges are generated on the columnar anode electrodes and also on the strip-shaped cathodes and these electric charges are observable to determine the anode or cathode strip at which this amplification phenomenon occurs and thus to obtain information as to position of the incident particle beam.Type: GrantFiled: February 22, 2002Date of Patent: November 23, 2004Assignee: Japan Science and Technology CorporationInventors: Toru Tanimori, Atsuhiko Ochi
