Patent ID: 7609058

Claim:
A method for generating a magnetic resonance (MR) data file, comprising the steps of: acquiring MR raw data from an examination subject using an MR imaging sequence; establishing k-space in a computer storage medium and dividing k-space into a contiguous central region and a contiguous peripheral region surrounding said central region; in a computerized procedure, entering said raw data into k-space at a constant sampling rate for both of said central and peripheral regions, by scanning said central region and said peripheral region alternatively a plurality of times and, during each scan of said peripheral region, scanning different sampling points in k-space with respect to the preceding scan of said peripheral region or with respect to the following scan of said peripheral region, while sampling said central region with a first sampling density of sampling points in k-space and sampling said peripheral region at a second sampling density of sampling points in k-space that is less than first sampling density, thereby producing sampled k-space; and making sampled k-space available in a data tile, in a form suitable for conversion into an image file, as an output from said computerized procedure.
