  • Patent number: 8811707
    Abstract: A system and method for distributed and coordinated image processing of tomographic images utilizing processors on a medical imaging device and a separate workstation is disclosed. The system includes an image acquisition device to acquire image data of a subject and an image processor to receive the image data therefrom. The image processor is programmed to reconstruct initial images of a region-of-interest (ROI) from the image data, identify initial images on which to perform image correction, and generate an image correction request for the images identified for image correction, with the image correction request specifying a processing operation to be performed on the respective images. The image processor is further programmed to transfer the reconstructed initial images to a separate workstation that automatically initiates the image correction upon verifying a presence of an image correction request on the initial images so as to generate corrected images.

  • Patent number: 8224056
    Abstract: A method and system for motion estimation and compensation are disclosed. Initially, a set of one or more initial images is reconstructed using acquired imaging data. Further, one or more regions of interest are identified in this set of reconstructed initial images. At least a set of filters is applied to the identified regions of interest to generate a sequence of filtered images. Particularly, each of the filtered images in the generated sequence of filtered images includes data acquired near a different reference point. Subsequently, a motion path corresponding to each region of interest is determined based on one or more correspondences in the sequence of filtered images.

  • Patent number: 7382852
    Abstract: One or more techniques are provided for adapting a reconstruction process to account for the motion of an imaged object or organ, such as the heart. In particular, projection data of the moving object or organ is acquired using a slowly rotating CT gantry. Motion data may be determined from the projection data or from images reconstructed from the projection data. The motion data may be used to reconstruct motion-corrected images from the projection data. The motion-corrected images may be associated to form motion-corrected volume renderings.

  • Patent number: 7054475
    Abstract: A method for volumetric reconstruction of a cyclically moving object using a computed tomography (CT) system includes scanning a cyclically moving object with a CT imaging system including at least one of an area detector and a linear detector to encompass the desired field of view and a rotating gantry to measure projection data during a plurality of cycles of the cyclically moving object. The method also includes dividing a period of the cyclically moving object into a discrete number of phases, identifying an initial set of projection data at a desired phase of a first cycle at a first angle, identifying at least one subsequent set of projection data at the same desired phase of a subsequent cycle at an angle that is different from the first angle, and combining the initial set of projection data with each subsequent set of identified projection data and using a reconstruction algorithm to generate a three-dimensional image.

  • Patent number: 6956926
    Abstract: A technique is provided for improving consistency between slabs in a reconstructed CT image. Candidate sectors associated with an image slab are determined. If the sectors contain sufficient information to reconstruct the image slab, the sector which minimizes inconsistency with projection data for adjacent image slabs is selected for reconstruction. If the sectors do not contain sufficient information to reconstruct the slab, sectors are merged together until a merge group contains sufficient information. The merge group which minimizes inconsistency with projection data for adjacent image slabs is selected for image reconstruction. The selected sectors or merge groups are then reconstructed with the resulting image slabs comprising a reconstructed image with improved consistency between image slabs.

  • Patent number: 6765983
    Abstract: A technique is provided for reducing motion-related artifacts present in CT images attributable to the dynamic nature of the imaged tissue or the time-varying concentration of a contrast agent. A region of interest that encompasses a structure of diagnostic significance is selected. For projections acquired by the various rows of detectors in a multi-slice CT imaging system, the portions of the projections attributable to the projection of the region of interest are averaged for each view angle. The projections containing these averaged values are then combined with the projections which do not encompass the region of interest. The combined projection set may be reconstructed to form a CT image of the dynamic tissue. In addition, a smoothing step may be performed to interpolate projection values around the region of interest to smooth the visual transition to the unaveraged portions of the image.
