Patent ID: 7482806

Claim:
A method for data acquisition and image reconstruction in magnetic resonance tomography using a plurality of reception coils to respectively receive magnetic resonance signals, said magnetic resonance signals being entered into k-space, said method comprising the steps of: sampling the data in k-space with a plurality of blades each containing a plurality of k-space lines, by partially under-sampling at least one blade in said plurality of blades by regular omission of k space lines respectively at opposite boundary regions of each partial under-sampled blade, with regard to the phase-encoding direction of the blade such that only data in each A-th line of said boundary regions are acquired, with no omission of k space lines in a central region of the blade (with regard to the phase-encoding direction), to obtain at least one coil calibration line; selecting a partial parallel acquisition (PPA) technique for completion of the respective blades and determining coil calibration data for the PPA reconstruction of a particular partial under-sampled blade from the central completely sampled region of said blade; executing PPA reconstruction for the selected PPA technique, including interpolating the omitted k space lines of each blade; accelerating said PPA reconstruction by executing a coil-exclusion algorithm that excludes signal contributions from respective coils in said plurality of coils, said algorithm excluding respective signal contributions that are not significant to said PPA reconstruction; and executing a PROPELLAR reconstruction after said PPA reconstruction.
