Methods And Apparatus For Cone Beam Multislice Ct Correction

View page
US Patent:
6459754, Oct 1, 2002
Filed:
Oct 27, 1999
Appl. No.:
09/428183
Inventors:
Guy M. Besson - Wauwatosa WI
Sarah K. Patch - Milwaukee WI
Assignee:
GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:
A61B 603
US Classification:
378 4, 378 15, 378901
Abstract:
The present invention is, in one embodiment, a method for multi-slice, computed tomography imaging. The method includes steps of moving an x-ray source through a trajectory; projecting an x-ray cone beam from the moving x-ray source through an object towards a curved detector; and determining contributions of segments along the trajectory to voxels in a reconstruction volume of the object, including compensating the determined contributions for curvature of the detector and x-ray cone beam geometry.

System And Method For Unwrapping Phase Difference Images

View page
US Patent:
6703835, Mar 9, 2004
Filed:
Apr 11, 2002
Appl. No.:
10/119724
Inventors:
Sarah K. Patch - Milwaukee WI
Tejaswini Shubhachint - Waukesha WI
Graeme C. McKinnon - Hartland WI
Sandhya Parameswaran - Gurnee IL
Joseph K. Maier - Milwaukee WI
Assignee:
GE Medical Systems Global Technology Co. LLC - Waukesha WI
International Classification:
G01N 300
US Classification:
324307
Abstract:
A method for processing digital images includes acquiring a phase difference image which includes one or more phase wraps, creating a modulated phase difference image from the phase difference image, comparing the modulated phase difference image to the phase difference image to locate areas in the phase difference image to be unwrapped, and unwrapping the phase difference image based on the areas located in the comparing step. The unwrapping step is performed by replacing wrapped pixels in the phase difference image with pixels in the modulated phase difference image plus an integer multiple of. The integer multiplier is computed by comparing overlapping pixels in the image segments. This has a smoothing effect causing the wrapped pixels in the phase difference image to become unwrapped. As a result of this pixel replacement process, an image of improved quality and information content is produced compared with conventional methods.

Methods And Apparatus For Weighting Of Computed Tomography Data

View page
US Patent:
6754299, Jun 22, 2004
Filed:
Aug 2, 2002
Appl. No.:
10/211206
Inventors:
Sarah K. Patch - Milwaukee WI
Assignee:
GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:
A61B 603
US Classification:
378 15, 378 8, 378901
Abstract:
A method for reconstructing an image of an object utilizing a computed tomographic (CT) imaging system is provided. The CT system includes a radiation source and a multislice detector array on a rotating gantry, with the radiation source configured to project a beam of radiation through an object and towards. the multislice detector array. The multislice detector array is configured to sense attenuation of the radiation passing through the object. The method for reconstructing an image includes helically scanning an object with a computed tomographic imaging system to acquire a plurality of views of projection data at a plurality of gantry angles and a plurality of cone angles, generating a plurality of cone angle dependent weights that are inversely correlated to an absolute value of a cone angle, and weighting the projection data using the cone angle dependent weights.

Three Dimensional Back Projection Method And An X-Ray Ct Apparatus

View page
US Patent:
6845144, Jan 18, 2005
Filed:
Feb 8, 2003
Appl. No.:
10/360588
Inventors:
Akihiko Nishide - Tokyo, JP
Sarah K. Patch - Milwaukee WI, US
Assignee:
GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:
A61B 603
US Classification:
378 15, 378901
Abstract:
To perform cone beam reconstruction by using projection data correctly corresponding to X-ray beam having passed through each pixel in the reconstruction area, data Dis obtained which is plane projected to a plane based on projection data D. Then, plane projection data Dto the projection plane pp is projected to the reconstruction area in the direction of X-ray transmission to obtain back projection pixel data D. Thereafter, back projection pixel data Dwill be added for each corresponding pixel for all views to obtain back projection data D. The present invention provides reconstruction by device of projection data correctly corresponding to the X-ray beam having passed through the reconstruction area. Through the plane projection to a plane the operation will become simplified and faster.

Method And System Of Determining In-Plane Motion In Propeller Data

US Patent:
7176684, Feb 13, 2007
Filed:
Jun 29, 2005
Appl. No.:
11/170054
Inventors:
Sarah K. Patch - Milwaukee WI, US
Michael R. Hartley - Novi MI, US
James G. Pipe - Glendarle AZ, US
Assignee:
General Electric Company - Schenectady NY
Catholic Healthcare West, California Nonprofit Public Benefit Corporation, d/ba St. Joseph's Hospital and Medical Center - Phoenix AZ
International Classification:
G01V 3/00
US Classification:
324307, 324309
Abstract:
The present invention is directed to a method of MR imaging whereby a k-space blade extending through a center of k-space from a subject in motion is acquired. A high-pass convolution of the k-space blade with a reference k-space blade is then determined and converted to a δ function. In-plane motion of the subject during data acquisition of the k-space is then determined from the δ function.

Method And System Of Thermoacoustic Computed Tomography

View page
US Patent:
8529449, Sep 10, 2013
Filed:
Mar 15, 2004
Appl. No.:
10/800957
Inventors:
Sarah K. Patch - Milwaukee WI, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
A61B 8/00
US Classification:
600438, 378 4, 600407, 600425
Abstract:
The present invention is a directed to method and system of TCT imaging whereupon data associated with unmeasured or inadmissible transducer locations is determined from data acquired at measured or admissible transducer locations. The invention analyzes measured TCT data associated with several transducer locations to provide an estimate of unmeasured data so as to complete a full data set for image reconstruction. In this regard, by measuring TCT data at many points on the surface of a hemispherical bowl or sphere in which an imaging object is placed, mathematical coefficients may be determined for the TCT data as a function of transducer location. From these coefficients, the unmeasured transducer locations may be evaluated such that data associated with the unmeasured transducer locations may be estimated and utilized for image reconstruction to improve image quality as well as improve the diagnostic sensitivities or capabilities of the TCT system.
