  • Reduction of susceptibility artifacts in subencoded single-shot magnetic resonance imaging
    Patent number: 7298143
    Abstract: In a magnetic resonance imaging method an echo train is generated of successive magnetic resonance signals from an object to be examined. The magnetic resonance signals are received with a degree of undersampling and by means of a receiver antennae system having a spatial sensitivity profile and the degree of undersampling is set on the basis of an amount of phase evolution due to a magnetic susceptibility distribution of the object to be examined.

  • Retrospective selection and various types of image alignment to improve DTI SNR
    Patent number: 6724190
    Abstract: An imaging sequence, which generates a static image data set and a plurality of differently diffusion-weighted data sets, is repeated and the data sets stored in memories (360, 361, . . . , 36N). Each data set is reconstructed into corresponding images stored in sub memories (380, 381, . . . , 38N). The images are compared macroscopically (40) and shifted (42) into optimal alignment. Local regions of the images are analyzed (44) and adjusted (46) for better conformity. The static images and like spatially encoded images are compared with each other and those outside a preselected similarity threshold are rejected (48). The remaining like images are combined (50) and subject to a diffusion analysis (52) to generate an image of an anisotropic structure in the imaging region. The anisotropic structure and other image information are displayed on a monitor (58).
