Abstract
A device for MRI of a body () placed in an examination volume includes a main magnet () for establishing a substantially homogeneous main magnetic field in the examination volume. Gradient coils () generate switched magnetic field gradients superimposed upon the main magnetic field. An RF antenna () radiates RF pulses towards the body (). A control system () controls the generation of the magnetic field gradients and the RF pulses. A demodulator () receives and samples MR signals. A computer () forms MR images from the signal samples. The computer () is arranged to generate a series of MR signals by subjecting at least a portion of the body () to an MRI sequence, to acquire the MR signals as a plurality of k-space blades according to the PROPELLER scheme, to compute phase errors from the phase differences of pairs of k-space blades having different rotation angles, to perform a phase correction of the acquired k-space blades on the basis of the computed phase errors, and to reconstruct an MR image from the acquired and phase-corrected MR data set.
