US Patent:

7638776, Dec 29, 2009
Filed:

Aug 2, 2007
Appl. No.:

11/888843
Inventors:

Viatcheslav Vydrin - Pittsburgh PA, US
Assignee:

Endicott Interconnect Technologies, Inc. - Endicott NY
International Classification:

G01T 1/00
US Classification:

25037009
Abstract:

A radiation detection/imaging system includes a first set of radiation detectors spaced from each other in a first direction and a second set of radiation detectors spaced from each other in the first direction. The second set of radiation detectors is positioned laterally adjacent the first set of radiation detectors and the radiation detectors of the first and second sets of radiation detectors are arranged in an alternating or staggered pattern in the first direction. A composite image can be formed of the passage of radiation through an object acquired by the first and second sets of radiation detectors as the object is translated by the first and second sets of radiation detectors.

US Patent:

20040129887, Jul 8, 2004
Filed:

Aug 26, 2003
Appl. No.:

10/399810
Inventors:

Viatcheslav Vydrin - Pittsburgh PA, US
Robert Davis - Pittsburgh PA, US
Joseph Grosholz Jr - Natrona Heights PA, US
Kevin Parnham - Acton CA, US
International Classification:

G01T001/00
G01T001/20
US Classification:

250/367000
Abstract:

A gamma ray camera A includes a crystal array S which includes a plurality of pixels each of which outputs a pixel signal in response to receiving a gamma ray. A first circuit (and ) outputs for each pixel of the crystal array S, when a pixel signal output by the pixel has a predetermined relation to a reference signal, a threshold signal related to the position of the pixel in the crystal array S. A second circuit (and ) outputs a counter value for each pixel signal having a predetermined relation to its threshold signal. Lastly, a third circuit accumulates for each pixel of the crystal array S a count of the counter values output by the second circuit (and ) for the pixel

US Patent:

20080135771, Jun 12, 2008
Filed:

Mar 7, 2006
Appl. No.:

11/815343
Inventors:

Viatcheslav Vydrin - Pittsburgh PA, US
Robert K. Davis - Pittsburgh PA, US
David S. Rundle - Butler PA, US
Assignee:

II-VI INCORPORATED - Saxonburg PA
International Classification:

G01T 1/24
US Classification:

25037009
Abstract:

A radiation detection system is operative for converting () a radiation event into an electrical signal having an amplitude related to the energy of said radiation event, converting () at least a portion of the electrical signal into a count value related to the amplitude of the electrical signal and determining () the energy of the radiation event from the count value.
