Abstract:
1. A method to generate magnetic resonance (MR) images of an examination subject, comprising: operating a magnetic resonance data acquisition unit to excite nuclear spins in an examination subject and to detect MR signals simultaneously with multiple coils that occur as a result of the excitation, each of said multiple coils having an individual coil characteristic; entering data representing said MR signals into a memory representing a raw data space having a central raw data region and a further region outside of said central raw data region, by incompletely filling said raw data space with said signals representing said MR signals and undersampling said central raw data region with a coherent acquisition pattern comprised of a spatially repeating set of raw data points, and sampling said further region with an incoherent acquisition pattern; and in a processor, reconstructing an MR image from the data in said raw data space using a step-by-step iterative reconstruction algorithm with a reconstruction matrix starting from an initial estimate, said reconstruction matrix comprising information describing the respective individual coil characteristics of said multiple coils.
