In a data acquisition and reconstruction method for magnetic resonance
(MR) tomography, and a corresponding MR tomography apparatus, a
blade-like sampling of k-space according to the PROPELLER method using a
number of reception coils ensures with partial under-sampling of at least
one blade of k-space such that the under-sampling ensues by regular
omission of k-space lines in both boundary regions (with regard to the
phase-encoding direction k.sub.y) of a blade such that only data in each
A-th line of said boundary regions are acquired; with no k-space lines
being omitted in the central region (with regard to the
k.sub.y-direction) and thus at least one coil calibration line is
obtained, selection of a suitable PPA method for completion of the blades
and determination of the necessary coil calibration data necessary for
the PPA reconstruction of a partial under-sampled blade from the central
completely sampled region of said blade. PPA reconstruction via
application of the selected PPA method selected in order to interpolate
the non-measured or, respectively, omitted k-space lines of each blade,
and execution of the PROPELLER reconstruction after the PPA
reconstruction.
