摘要:
The invention relates to a method of MR imaging of an object (10) placed in an examination volume of a MR device (1). The method comprises the steps of: —subjecting the object (10) to an imaging sequence comprising phase-modulated multi-slice RF pulses for simultaneously exciting two or more spatially separate image slices, —acquiring MR signals, wherein the MR signals are received in parallel via a set of at least two RF coils (11, 12, 13) having different spatial sensitivity profiles within the examination volume, and —reconstructing a MR image for each image slice from the acquired MR signals, wherein MR signal contributions from the different image slices are separated on the basis of the spatial sensitivity profiles of the at least two RF coils (11, 12, 13) and on the basis of the phase modulation scheme of the RF pulses. In order to optimize the conditioning of the inverse problem of the MR image reconstruction, the phase-modulation scheme of the RF pulses is derived from the spatial sensitivity profiles of the at least two RF coils (11, 12, 13). Moreover, the invention relates to a MR device for carrying out this method as well as to a computer program to be run on a MR device.
