  • Method and apparatus for improving the quality of MR images sensitized to molecular diffusion
    Patent number: 8334695
    Abstract: In a method and apparatus for magnetic resonance (MR) imaging of an object, and in particular MR imaging that yields images sensitive to molecular diffusion, undesired image artifacts induced by the rhythmic motion of the apparatus are reduced by manipulating the amplitude, phase, and timing of the diffusion encoding gradient pulses in a manner that interrupts, diminishes, or cancels the rhythmic motion. The residual vibration is evaluated manually or automatically to make such manipulations.
    Type: Grant
