Filed:

Dec 22, 2009
Appl. No.:

12/644551
Inventors:

Peter R. Menge - Chagrin Falls OH, US
Louis Perna - Elyria OH, US
Assignee:

Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA
International Classification:

G01T 1/20
US Classification:

250368
Abstract:

A scintillation reflector can include a specular material having a first and second surface, and a first diffuse material arranged adjacent to the first surface of the specular material and proximal to the scintillator surface. The composite reflector may surround at least a portion of a scintillator surface as provide in a scintillation detector.

US Patent:

8598529, Dec 3, 2013
Filed:

Aug 29, 2011
Appl. No.:

13/220524
Inventors:

Louis Perna - Elyria OH, US
Assignee:

Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA
International Classification:

G01T 1/20
US Classification:

250361R
Abstract:

A process of forming a radiation detection system can include forming an array of scintillator elements, which can include joining a plurality of pieces including scintillator material together to form an object. A joining region can include the space between the immediately adjacent pieces. The process can also include cutting the object to obtain a portion having a face, wherein cutting is performed such that the portion includes parts of different pieces within the plurality of pieces. The process can further include cutting a groove within the portion, wherein the groove extends from the face and intersects the joining region. The process can include optically coupling the array to a photosensor. A radiation detection system can include an array of scintillator elements wherein a reflective sheet may lie between a pair of scintillator elements and no reflective sheet between another pair of scintillator elements.

US Patent:

20110042571, Feb 24, 2011
Filed:

Aug 23, 2010
Appl. No.:

12/861221
Inventors:

Louis Perna - Elyria OH, US
Assignee:

SAINT-GOBAIN CERAMICS & PLASTICS, INC. - Worcester MA
International Classification:

G01T 1/20
C09J 5/00
US Classification:

250361 R, 2504842, 1563066
Abstract:

The present disclosure relates to a scintillation assembly. The assembly may include a scintillator having a surface, a pressure sensitive adhesive layer contacting at least a portion of said surface, and a reflector proximal to the scintillator surface and adhered to the scintillator surface by the pressure sensitive adhesive layer, wherein the adhesive layer exhibits a TTV of 0.01 mm or less.

US Patent:

20130092828, Apr 18, 2013
Filed:

Sep 30, 2012
Appl. No.:

13/632046
Inventors:

Louis Perna - Elyria OH, US
Michael L. Bush - Ravenna OH, US
Lance J. Wilson - Shaker Heights OH, US
International Classification:

G01T 1/20
G01V 5/04
US Classification:

250256, 250361 R
Abstract:

A scintillator device includes an optically clear substrate, a scintillator plastic layer overlying the optically clear substrate, and an optically clear polymer layer between the optically clear substrate and the scintillator plastic layer. The optically clear polymer layer can mechanically and optically couple the scintillator plastic layer to the optically clear substrate. Further, the clear polymer layer can be configured to substantially reduce the formation of cracks in the scintillator plastic layer due to thermal expansion, thermal contraction, or a combination thereof, of the scintillator device.

US Patent:

20130193331, Aug 1, 2013
Filed:

Dec 15, 2012
Appl. No.:

13/716105
Inventors:

Louis Perna - Elyria OH, US
Assignee:

SAINT-GOBAIN CERAMICS & PLASTICS, INC. - Worcester MA
International Classification:

G01T 1/20
US Classification:

250366, 29428
Abstract:

A scintillator pixel array can include a housing and a plurality of scintillator pixels within the housing. Further, the scintillator pixel array can include a grid structure within the housing. The grid structure can separate the plurality of pixels into rows and columns. Further, the grid structure can include an opaque layer configured to substantially prevent pixel-to-pixel cross talk within the plurality of scintillator pixels.

US Patent:

20130200266, Aug 8, 2013
Filed:

Dec 12, 2012
Appl. No.:

13/712360
Inventors:

Louis Perna - Elyria OH, US
Assignee:

SAINT-GOBAIN CERAMICS & PLASTICS, INC. - Worcester MA
International Classification:

G01T 1/20
US Classification:

250366, 2504861, 216 24
Abstract:

A scintillator pixel array can include a plurality of scintillator pixels and a plurality of voids arranged in a checkerboard pattern. Each void can be defined by at least two surfaces having an adhesive disposed thereon. The scintillator pixel array can be made by fabricating an array of scintillator members and dissolvable members and dissolving the dissolvable members in a solvent.
