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 plurality from other of said data;(b) reconstructing at least a portion of the data using a Fourier Transform;(c) test reconstructing at least a portion of an image, from the portion of the reconstructed data, using a set of reconstruction parameters, comprising at least one reconstruction parameter wherein said least one reconstruction parameter comprises at least one phase correction;(d) measuring an image quality measure related to ghosting of the test reconstructed image;(e) automatically repeating (c) and (d) for a plurality of sets of reconstruction parameters to acquire an acceptable reconstructed image using the same reconstructed data of at least a portion of the data,wherein (d) comprises automatically selecting at least one region of interest (ROI) of said image and measuring said image quality measure only on said at least one ROI.
