Method And Apparatus For Scatter Measurement Using An Occluded Detector Ring
view source
US Patent:

6789943, Sep 14, 2004
Filed:

Nov 12, 2002
Appl. No.:

10/292985
Inventors:

Geordie Henry Zapalac - Grass Valley CA
Assignee:

GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:

G01D 1800
US Classification:

378207, 378 18
Abstract:

Certain embodiments include a system and method for scatter measurement and correction. The method includes performing a calibration scan using a phantom to measure a scatter signal ratio between scatter x-rays impacting a first detector ring and scatter x-rays impacting a second detector ring. The scatter signal ratio is used to determine a scatter scale factor. The method further includes positioning a collimator such that the first detector ring is occluded from a path of primary x-rays generated by a target. The method also includes executing a low exposure scan to obtain x-ray scatter data using the first detector ring and the second detector ring and applying the scatter scale factor to the scatter data to produce scaled scatter data. The method further includes obtaining image data using the first detector ring and/or the said second detector ring and adjusting the image data using the scaled scatter data.

US Patent:

6842499, Jan 11, 2005
Filed:

Nov 15, 2002
Appl. No.:

10/065757
Inventors:

Geordie Henry Zapalac - Grass Valley CA, US
Assignee:

GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:

G01N 2300
US Classification:

378 12, 378 4, 378901
Abstract:

A method and apparatus are disclosed in an EBT scanner for generating an image from a data set collected from a subject beginning at an arbitrary time within a scanning time interval. A sequence of temporally separated, unfolded parallel view sinograms are generated corresponding to scans through the subject during the scanning time interval. Data from each of the sinograms are folded into each other such that loss of information and image artifacts, caused by temporal separation between temporally adjacent sinograms, are greatly reduced. An image is generated from a subset of data taken from the folded sinograms wherein the subset of data begins at an arbitrary time within the scanning time interval.

International Classification:

G01N020/083
US Classification:

378 62, 378 8, 378901
Abstract:

A method for facilitating a reduction in motion artifacts includes comparing two sequential scanned images to determine motion.

Defect Detection Using Time Delay Lock-In Thermography (Lit) And Dark Field Lit

US Patent:

7709794, May 4, 2010
Filed:

Feb 5, 2008
Appl. No.:

12/026539
Inventors:

Guoheng Zhao - Milpitas CA, US
Geordie Zapalac - Santa Cruz CA, US
Samuel Ngai - San Francisco CA, US
Mehdi Vaez-Iravani - Los Gatos CA, US
Ady Levy - Sunnyvale CA, US
Vineet Dharmadhikari - San Jose CA, US
Assignee:

KLA-Tencor Corporation - San Jose CA
International Classification:

G01J 5/00
US Classification:

2503381, 250334
Abstract:

To increase inspection throughput, the field of view (FOV) of an IR camera can be moved over the sample at a constant velocity. Throughout this moving, a modulation (e. g. optical or electrical) can be provided to the sample and IR images can be captured using the IR camera. Moving the FOV, providing the modulation, and capturing the IR images can be synchronized. The IR images can be filtered to generate the time delay LIT, thereby providing defect identification. In one embodiment, this filtering accounts for the number of pixels of the IR camera in a scanning direction. For the case of optical modulation, a dark field region can be provided for the FOV throughout the moving, thereby providing an improved signal-to-noise ratio (SNR) during filtering.

US Patent:

20190036479, Jan 31, 2019
Filed:

Jul 26, 2017
Appl. No.:

15/660086
Inventors:

- Beijing, CN
Geordie ZAPALAC - Santa Clara CA, US
International Classification:

H02S 30/00
H02S 20/23
Abstract:

Various embodiments include a solar panel having a bottom surface adjacent to the base layer having a curved shape configured to generate a downward force when subject to wind. The bottom surface may be an outer surface of the base layer that has a convex shape. The bottom surface may be integral to the base layer and have a convex shape. The bottom surface may be a shell coupled to the base layer with an outer surface that has a convex shape. Such a shell may form a void space between the shell and the base layer. By exhibiting a convex shape, the bottom surface may generate a downward force in wind due to Bernoulli's Principle that helps to resist wind forces that would otherwise tear the panel from its mountings.
