methods for diffusion-weighted magnetic resonance imaging and for designing an asymmetric time-dependent magnetic field gradient.

摘要

according to an aspect of the present inventive concept, a method for diffusion-weighted magnetic resonance imaging is provided, which comprises: generating, by a gradient coil of a magnetic resonance imaging scanner, a field gradient time-dependent magnetic, where the gradient is asymmetric in time with respect to the reorientation pulse and where the gradient is such that it is zero, that is an echo time and is a time function that is positive during a previous interval to the reorientation pulse and negative for a period of time after the reorientation pulse.
