Apparatus For Fine-Delay Adjustments Of Analog Signals In Positron Emitter Tomography Sensors

View page
US Patent:
8198597, Jun 12, 2012
Filed:
Oct 29, 2010
Appl. No.:
12/916071
Inventors:
Kent Burr - Buffalo Grove IL, US
Daniel Gagnon - Twinsburg OH, US
John Jedrzejewski - Niles IL, US
Assignee:
Kabushiki Kaisha Toshiba - Tokyo
Toshiba Medical Systems Corporation - Otawara-shi
International Classification:
G01T 1/164
US Classification:
25037009, 25037011, 250371, 250362, 2503562
Abstract:
A variable delay device is connected to a photosensor of a time-of-flight gamma ray detection system and includes a substrate on which a plurality of conductive pins are affixed. A first terminal connected to a first of the plurality of pins and a second terminal connected to the second of the plurality of pins are also affixed to the substrate. A jumper electrically connects the plurality of pins at a predetermined distance relative to the substrate, and a time delay of the variable delay device is determined based on the electrical path between the first and second terminals formed by the plurality of pins and the jumper.

US Patent:
8446308, May 21, 2013
Filed:
Apr 21, 2011
Appl. No.:
13/091985
Inventors:
Kent Burr - Buffalo Grove IL, US
Gin-Chung Wang - Grayslake IL, US
John S. Jedrzejewski - Niles IL, US
Gregory J. Mann - Wheaton IL, US
Assignee:
Kabushiki Kaisha Toshiba - Tokyo
Toshiba Medical Systems Corporation - Otawara-shi
International Classification:
H03M 1/12
US Classification:
341156, 327 51, 327 69, 327 70, 375354, 375376, 363 41
Abstract:
A system and method for processing an analog signal output by a sensor. The system and method converting, using at least one analog-to-digital converter (ADC), the analog output signal to a digital signal, the digital signal including a plurality of samples at a predetermined resolution, detecting whether a trigger condition is met by analyzing the digital signal, detecting an event based on trigger information from the detecting whether a trigger condition is met, generating event information having time information included therein when the event is detected, defining one or more time windows based on the time information included in the event information, performing decimation on the digital signal based on the defined one or more time windows to generate a decimated signal, and outputting the decimated signal.
