  • Highly constrained reconstruction of motion encoded MR images
    Patent number: 7711166
    Abstract: A series of velocity encoded MR image frames are acquired. To increase the temporal resolution of the acquired image frames radial projections are acquired and each image frame is highly undersampled. The radial projections for each velocity encoding direction are interleaved throughout the scan and a composite phase image is reconstructed from these and used to reconstruct a velocity image for each image frame in a highly constrained backprojection method.
    Type: Grant

    Date of Patent: May 4, 2010

  • Reconstruction method for images of the beating heart
    Patent number: 7647088
    Abstract: Projection views of the moving heart and stationary background tissues are acquired and processed to provide corresponding moving tissue projection views. An average image is reconstructed in a conventional manner and a moving tissue image is reconstructed using a highly constrained backprojection method and a composite image formed from selected moving tissue projection views. The average image is then combined with the moving tissue image. The method is disclosed in a cardiac gated MRI scan.

  • Highly constrained magnetic resonance spectroscopy image reconstruction method
    Patent number: 7408347
    Abstract: A series of image frames are acquired in which an MR parameter such as echo time (TE) is changed and the resulting image frames are employed to produce an MRS image of a metabolite. Scan time is reduced without sacrificing image quality by reconstructing a composite image from data acquired for a plurality of the image frames and using a highly constrained image reconstruction method with the composite image to produce each image frame.
