Abstract
A method of iterative reconstruction for MRI imaging, comprising: (a) acquiring data into a k-space, wherein some of said data is acquired using an opposite gradient polarity from other of said data; (b) partially reconstructing at least a portion of the data, using a Fourier transform; (c) test reconstructing, at least a portion of an image, from the partially reconstructed data, using a set of reconstruction parameters, comprising at least one reconstruction parameter; (d) measuring an image quality measure of the test reconstructed image; and (e) automatically repeating (c) and (d) for a plurality of sets of reconstruction parameters to determine an acceptable reconstructed image, using the same partially reconstructed data.
