  • Patent number: 7244063
    Abstract: An imaging system for scanning a volume of interest in an object, the system includes a radiation source configured to traverse in a plurality of focal spot positions yielding a plurality of focal spot trajectories. Each focal spot trajectory defines a two dimensional focal spot projection in an image acquisition plane. Each of the focal spot positions comprise at least two positions at unequal distances from the image acquisition plane.

  • Publication number: 20070052700
    Abstract: A technique is provided for performing a computer aided detection (CAD) analysis of a three-dimensional volume using a computer assisted detection and/or diagnosis (CAD) algorithms. The technique includes selecting one or more three-dimensional points of interest in a three-dimensional volume, forward projecting the one or more three-dimensional points of interest to determine a corresponding set of projection points within one or more two-dimensional projection images, and computing output values at the one or more three-dimensional points of interest based on one or more feature values or a CAD output at the corresponding set of projection points.

  • Publication number: 20070014448
    Abstract: A technique is provided for comparative image analysis and/or change detection using computer assisted detection and/or diagnosis (CAD) algorithms. The technique includes registering a first three-dimensional image of a first volume and a second three-dimensional image of a second volume. The first and the second volume are generally anatomically symmetric to one another. The technique also includes automatically comparing the first three-dimensional image and the second three-dimensional image.

  • Publication number: 20070003118
    Abstract: A technique is provided for comparative image analysis and/or change detection using computer assisted detection and/or diagnosis (CAD) algorithms. The technique includes registering a three-dimensional image and a two-dimensional image, projecting the registered three-dimensional image to generate a reprojected two-dimensional image, and automatically comparing the two-dimensional image and the reprojected two-dimensional image.

  • Publication number: 20060291711
    Abstract: A method of creating and displaying images resulting from digital tomosynthesis performed on a subject using a flat panel detector is disclosed. The method includes the step of acquiring a series of x-ray images of the subject, where each x-ray image is acquired at different angles relative to the subject. The method also includes the steps of applying a first set of corrective measures to the series of images, reconstructing the series of images into a series of slices through the subject, and applying a second set of corrective measures to the slices. The method further includes the step of displaying the images or slices according to at least one of a plurality of display options.

  • Publication number: 20060067473
    Abstract: Briefly in accordance with one embodiment, the present technique provides a multi-energy tomosynthesis imaging system. The system includes an X-ray source configured to emit X-rays from multiple locations within a limited angular range relative to an imaging volume. The imaging system also includes a digital detector with an array of detector elements to generate images in response to the emitted X-rays. The imaging system further includes a detector acquisition circuitry to acquire the images from the digital detector. The imaging system may also include a processing circuitry configured to decompose plurality of images based on energy characteristics and to reconstruct the plurality of images to generate a three-dimensional multi-energy tomosynthesis image.

  • Publication number: 20050135664
    Abstract: Some configurations of method for reconstructing a volumetric image of an object include obtaining a tomosynthesis projection dataset of an object. The method also includes utilizing the tomosynthesis projection dataset and additional information about the object to minimize a selected energy function or functions to satisfy a selected set of constraints. Alternatively, constraints are applied to a reconstructed volumetric image in order to obtain an updated volumetric image. A 3D volume representative of the imaged object is thereby obtained in which each voxel is reconstructed and a correspondence indicated to a single one of the component material classes.

  • Publication number: 20050074158
    Abstract: Some configurations of the present invention provide a method for locating a low contrast movable object coupled mechanically to a marker object in a series of image frames that include images of the low contrast object and the marker object. The method includes locating the marker object in a first selected frame of the series of image frames, selecting a patch of the first selected frame as a template of the marker object, and utilizing the template of the marker object to estimate a location of the marker object in a second selected frame of the series of image frames. The second selected frame is registered with the first selected frame utilizing the estimated location of the marker object in the second selected frame. The registered first selected frame and the second selected frame are fused to thereby enhance the contrast of the low contrast moveable object.
