  • Methods and systems for an adaptive perfusion scan
    Patent number: 11452490
    Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon an injection of a contrast agent, initiating a contrast scan of a subject according to a fallback scan prescription, processing acquired projection data of an anatomical region of interest (ROI) of the subject to measure a contrast signal of the contrast agent, identifying a peak in the contrast signal within a predetermined time frame, if the peak in the contrast signal is not identified within the predetermined time frame, updating the fallback scan prescription to generate an adapted scan prescription for the contrast scan based on the contrast signal, and performing a remainder of the contrast scan according to the adapted scan prescription, and if the peak in the contrast signal is not identified within the predetermined time frame, continuing the remainder of the contrast scan according to the fallback scan prescription.

  • Methods and apparatus for reconstructing an image of an object
    Patent number: 6775347
    Abstract: A method for reconstructing an image of an object includes generating a plurality of projection data, helically interpolating the projection data, rebinning the helically interpolated projection data from a fan-beam format to a parallel-beam format, and reconstructing an image of the object using the parallel-beam format projection data.

  • Scan data correction view weighting of computed tomographic images
    Patent number: 6584165
    Abstract: One aspect of the present invention is a method for reconstructing computed tomographic (CT) images. The method includes generating a plurality of projection data, calculating a plurality of base weights using the projection data for each series of images to be reconstructed, storing the base weights in an external memory, and applying a z-smoothing module to the base weights to determine a plurality of final weights. The view weighting process then includes applying the final weights to the projection data for each image.

  • Helical rowwise view weighting of computed tomographic images
    Patent number: 6418184
    Abstract: One aspect of the present invention is a method for reconstructing an image of an object utilizing a computed tomographic (CT) imaging system. The method includes steps of: helically scanning an object; interpolating an axial fan beam set of projection data as a vector function {right arrow over (R)}a from a fan beam set of projection data from the helical scan {right arrow over (R)}hi, where i=1, . . .
