<p>A magnetic resonance (MR) imaging (MRI) system (100, 1500), including at least one controller (110, 1510) configured to: perform a multi-shot image acquisition process to acquire MR information for at least one multi-shot image set; train a convolution kernel comprising data on at least a portion of the MR information obtained without the use of the gradient or by using a self-training process, the convolution kernel including convolution data; iteratively convolve the MR information obtained with the use of a gradient for at least two of the image shots of the at least one multi-shot image set with the trained convolution kernel; project the synthetic k-space data for the at least two image shots of the at least one multi-shot image set into image space; and average the projected synthetic k-space data that are projected into the image space to form image information.</p> |
