Data Normalization In Inverse Geometry Computed Tomography System

View page
US Patent:
7860210, Dec 28, 2010
Filed:
Nov 18, 2008
Appl. No.:
12/273223
Inventors:
Norbert J. Pelc - Los Altos CA, US
Jongduk Baek - Menlo Park CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
A61B 6/00
US Classification:
378 9, 378 4
Abstract:
A method for imaging an object in a computed tomography (CT) system with a plurality of sources comprising a first source and a second source, wherein the plurality of sources together with a detector array are mounted on a rotatable gantry, and wherein an intensity of the second source has unknown fluctuations is provided. Projection data is collected using the first source in a first gantry position. Projection data is collected using the second source in a second gantry position, wherein projection data from the first source in the first gantry position substantially overlaps projection data from the second source in the second gantry position. Data from the first source at the first gantry position is used to correct for source fluctuations of the second source at the second gantry position.

US Patent:
20090067569, Mar 12, 2009
Filed:
Sep 7, 2007
Appl. No.:
11/851609
Inventors:
Jongduk Baek - Palo Alto CA, US
Norbert J. Pelc - Los Altos CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
A61B 6/03
G06K 9/00
US Classification:
378 4, 382131
Abstract:
A method for imaging unknown objects in a computed tomography (CT) system, comprising determining ray gain for a known object is provided. A CT reconstruction is performed with the known object to obtain reconstructed values. Ideal values are obtained for pixels of the known object. An error related to a difference between the reconstructed values and the ideal values is generated. A ray gain is estimated that reduces the error.
