International Classification:
G06K 9/38
US Classification:
382270
Abstract:
An imaging system includes an analog-to-digital converter configured to convert an analog pixel value into a first digital pixel value. The imaging system also includes an index value source configured to receive the first digital pixel value from the analog-to-digital converter and to generate a digital index value based on a comparison of the first digital pixel value to a digital reference value. In addition, the imaging system includes a transmitter in communication with the index value source and configured to transmit the digital index value. Further, the imaging system includes an image processing component configured to receive the digital index value and to generate a second digital pixel value based at least in part on the received digital index value and a lookup table of the image processing component.
System And Method For Correcting For Image Artifacts In X-Ray Image Data
US Patent:
2014005, Feb 20, 2014
Filed:
Aug 17, 2012
Appl. No.:
13/588832
Inventors:
James Zhengshe Liu - Salt Lake City UT, US
Assignee:
GENERAL ELECTRIC COMPANY - Schenectady NY
International Classification:
G06K 9/40, G01N 23/04
US Classification:
378 62, 382132
Abstract:
A computer-implemented method for reducing image artifacts in X-ray image data includes dividing pixels of X-ray image data into a plurality of pixel value regions based on a pixel value of each pixel, wherein each pixel value region has a different range of pixel values. The method also includes generating calibrated X-ray image data for each pixel value region, wherein the respective calibrated X-ray image data for each pixel value region is generated using a different dose of radiation. Further, the method includes calculating a gain slope for each pixel value region based on the calibrated X-ray image data, and calculating a pixel gain correction for the pixels of the X-ray image data based on at least one of the calculated gain slopes.
Gain Calibration Technique For Digital Imaging Systems
US Patent:
2014004, Feb 13, 2014
Filed:
Aug 7, 2012
Appl. No.:
13/568912
Inventors:
James Zhengshe Liu - Salt Lake City UT, US
Assignee:
GENERAL ELECTRIC COMPANY - Schenectady NY
International Classification:
G06K 9/38, G01N 23/04
US Classification:
378 62, 382131
Abstract:
A computer-implemented method for gain calibration is provided. The method includes sorting the calibration data of each pixel location from the offset-corrected X-ray image data into a sequence. The method also includes removing part of the calibration data from one end or both ends of the respective sequence for each pixel location. The method further includes averaging the calibration data remaining within each respective sequence to obtain an average pixel value for each pixel location. The method yet further includes generating a gain map based on the average pixel value for each pixel location.
