  • Magnetic resonance random trajectory collection method and apparatus
    Patent number: 6515477
    Abstract: In order to provide a magnetic resonance signal collection method and apparatus that suppress false images caused by motion of an imaged object, the order of selecting trajectories a-p is randomized. Alternatively, the angular difference is set at 90° between first and next trajectories, and then new trajectories are defined so that the angular difference between adjacent trajectories is a repeatedly bisected angle in sequence.
