Abstract: A magnetic resonance (MR) imaging (MRI) system (100, 1500), includes 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 including 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 includes convolution data. 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 is iteratively convolved with the trained convolution kernel. The synthetic k-space data for the at least two image shots of the at least one multi-shot image set is projected into image space. The projected synthetic k-space data that are projected into the image space to form image information.
