Compact Medical Imager

View page
US Patent:
6495834, Dec 17, 2002
Filed:
Oct 15, 1999
Appl. No.:
09/418903
Inventors:
Philip J. Corvo - Hudson OH
Michael R. Mayhugh - Shaker Heights OH
Scott T. Huth - Norton OH
Kenneth Smolko - Medina OH
Csaba M. Rozsa - Brecksville OH
Robert S. Schreiner - Chagrin Falls OH
Assignee:
Saint-Gobain Industrial Ceramics, Inc. - Worcester MA
International Classification:
G01T 120
US Classification:
2503631
Abstract:
A compact medical nuclear imaging device, which generates a medical image from gamma radiation, can be held stationary or moved to search a large area for locating a radioactive area of interest. The compact medical imaging device comprises a collimator having an array of collimating channels, a radiation collection module converting the gamma radiation to an electric signal, an electronic module for processing the electrical signal, and a display module for displaying a two-dimensional image of the radiation scene, all of which preferably are assembled together in a single, compact module of a size small enough to permit it to be held and maneuvered by a human operator.

Gamma Camera Plate Assembly For Pet And Spect Imaging

View page
US Patent:
6534771, Mar 18, 2003
Filed:
Mar 27, 2000
Appl. No.:
09/535715
Inventors:
Csaba M. Rozsa - Brecksville OH
Assignee:
Saint Gobain Industrial Ceramics, Inc. - Worcester MA
International Classification:
G01T 120
US Classification:
250367
Abstract:
A gamma camera scintillation crystal plate assembly and method that may be used for both PET (positron emission tomography) and SPECT (single photon emission computer tomography). The crystal plate assembly includes two or more crystals which are optically coupled and tuned so as to control the energy position of the photopeaks at an output surface of the plate assembly. The crystals are tuned by various means including varying the surface finishes and material selection.

Thick Scintillation Plate With Internal Light Collimation

View page
US Patent:
6563121, May 13, 2003
Filed:
Mar 2, 2000
Appl. No.:
09/517492
Inventors:
Robert S. Schreiner - Chagrin Falls OH
George Mataraza - Euclid OH
Csaba M. Rozsa - Brecksville OH
Assignee:
Saint Gobain Industrial Ceramics, Inc. - Worcester MA
International Classification:
G01T 1202
US Classification:
250368, 25037011
Abstract:
A gamma camera plate incorporates scintillation crystal which is sufficiently thick to effectively capture high energy radiation. The crystal is provided on its light output side with an array of light path-modifying partitions which extend partly through its thickness. These partitions define individual light collimating cells which reduce the light spreading which would otherwise prevent effective use of the plate for low energy radiation.

Thick Scintillation Plate With Internal Light Collimation

US Patent:
6881960, Apr 19, 2005
Filed:
Mar 24, 2003
Appl. No.:
10/395325
Inventors:
Robert S. Schreiner - Chagrin Falls OH, US
George Mataraza - Euclid OH, US
Csaba M. Rozsa - Brecksville OH, US
Assignee:

Scintillation Detector, System And Method Providing Energy And Position Information

View page
US Patent:
6909097, Jun 21, 2005
Filed:
Apr 3, 2002
Appl. No.:
10/115596
Inventors:
Robert S. Schreiner - Chagrin Falls OH, US
John A. White - Chagrin Falls OH, US
Michael R. Mayhugh - Shaker Heights OH, US
George Mataraza - Euclid OH, US
Csaba M. Rozsa - Chagrin Falls OH, US
Daniel J. Herr - Twinsburg OH, US
Assignee:
Saint Gobain Ceramics and Plastics, Inc. - Worchester MA
International Classification:
G01T001/202
US Classification:
250366, 250367
Abstract:
A radiation detector, in particular a gamma camera, is constructed and operated in such a fashion that only a predetermined number of light sensors (such as PMT's) adjoining each other in a cluster are used to generate a signal with amplitude and event position information. The camera may also use an array of individual scintillation elements (crystals) in place of a single crystal, with certain advantages obtained thereby. According to another aspect of the invention, there is a reflector sheet that defines an array of apertures through which scintillation light can pass from the scintillation crystal to a plurality of light sensors optically coupled to an optical window in an array corresponding to the array of apertures in the reflector.

Apparatus Employing A Filtered Scintillator And Method Of Using Same

View page
US Patent:
7138633, Nov 21, 2006
Filed:
Jan 23, 2004
Appl. No.:
10/764342
Inventors:
Csaba M. Rozsa - Brecksville OH, US
George A. Mataraza - Euclid OH, US
Assignee:
Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA
International Classification:
G01T 1/20
US Classification:
250368, 250361 R
Abstract:
A scintillation detector apparatus comprising a filter disposed intermediate a scintillator and a detector, the filter being adapted to block relatively long wavelengths of light to reduce afterglow. The detector apparatus may, for example, be a part of a detector system such as a CT scanner, a RG system, or a geophysical measurement system.

Assignee:
Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA
International Classification:
G01T 1/20
US Classification:
25037011
Abstract:
A radiation detector device is disclosed that includes a scintillator including a scintillator crystal and a hybrid photodetector (HPD) coupled to the scintillator.

Further, the hybrid photodetector includes an electron detector adapted to receive photoelectrons emitted by the photocathode. The electron detector comprises a semiconductor material characterized by a bandgap of at least 2.15 eV.
