A method for generating motion-corrected medical images includes obtaining, via a processor, k-space data of a region of interest acquired by a magnetic resonance imaging system utilizing a 3D radial pulse sequence with ZTE acquisition including optional magnetization preparation pulses. The method also includes sampling, via the processor, the k-space data to obtain a plurality of interleaved k-space segments. The method further includes reconstructing, via the processor, one or more interleaved k-space segments of the plurality of interleaved k-space segments to generate a respective motion navigator volume. The method even further includes co-registering, via the processor, each respective motion navigator volume to estimate motion and performing motion correction on the one or more interleaved k-space segments and their corresponding k-space trajectories. The method still further includes generating, via the processor, a motion-corrected volume from all of the motion corrected interleaved k-space segments and their corresponding motion corrected k-space trajectories.

System and method for performing motion-insensitive and quiet three-dimensional magnetic resonance imaging

The present invention provides a method and system to reduce the problem of signal dropout in data acquired using gradient-echo and asymmetric spin-echo magnetic resonance techniques, caused by linear susceptibility gradients in the direction of slice-selection. Specifically an algorithm is used to determine the optimal parameters of a tailored radiofrequency pulse along with the accompanying slice-selection and slice-refocusing gradients to correct this signal dropout.
