  • Systems, methods and apparatus for plaque visualization and quantification using fuzzy and adaptive region classes
    Patent number: 8406488
    Abstract: Systems, methods and apparatus are provided through which coronary plaque is classified in an image and visually displayed using an iterative adaptive process, such as an expectation maximization process.
    Type: Grant
    Filed: November 23, 2006
    Date of Patent: March 26, 2013
    Assignee: General Electric Company

  • Method and system for automatically identifying and displaying vessel plaque views
    Patent number: 8126238
    Abstract: A method for processing computed tomography (CT) datasets comprises identifying regions of interest (ROIs) within a CT dataset is provided. The ROIs are ranked based on a comparison to at least one predetermined parameter. The ranking determines a level of importance for the ROIs with respect to each other. A list of the ROIs is provided on a display, the list indicating the ROIs based on an associated level of importance. The ROIs are selectable with a user interface.

  • Methods and systems for optimizing high resolution image reconstruction
    Patent number: 8081809
    Abstract: Methods and apparatus for reconstructing a multiple resolution images of an object are provided. The method includes reconstructing a first three-dimensional image at a first resolution, determining at least one volume of interest in the generated image, and reconstructing a second three-dimensional image of the determined at least one volume of interest at a second resolution, the second resolution being higher than the first resolution such that a quantification of image structures is facilitated.

  • Methods and systems for enhanced plaque visualization
    Patent number: 8077939
    Abstract: Methods and apparatus for coding a visual representation of one or more plaque regions in a vessel are provided. The method includes segmenting the visual representation of the vessel to identify structures associated with the vessel, classifying at least one region in the vessel as a plaque region, displaying the at least one plaque region using a visual highlight selectively associated with the classification for the at least one plaque region, and shading the visual highlight based on a probability that the classification is correct.

  • Methods and apparatus for generating a risk metric for soft plaque in vessels
    Patent number: 7957574
    Abstract: A method for generating a score for soft plaque in coronary arteries includes using the computer to estimate the soft plaque content within at least one object depicted in a medical image, using the computer to determine a plaque score dependent upon the estimated soft plaque content of the at least one object, and using the computer to report the plaque score.

  • Method and system for adjusting 3D CT vessel segmentation
    Patent number: 7940974
    Abstract: Method and system for processing an object within a diagnostic image comprises segmenting a three dimensional (3D) object within a diagnostic image. A contour of the object is fitted with a 3D mesh comprising splines in at least first and second directions. The splines provide a plurality of editable control points, and the splines in the first direction intersect with the splines in the second direction at intersection points. A position of at least one control point on the 3D mesh is adjusted based on a user input.

  • Method and system for creating and using an impact atlas
    Patent number: 7912270
    Abstract: A method and system for processing a cardiac image dataset acquired from an imaging system is provided. A location of a first potential blockage point within a first cardiac vessel is located. A functional impact of the first potential blockage point on the cardiac tissue is predicted, and a representation of the functional impact is provided.
