Patent ID: 11815577

Abstract:
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: —generating MR signals by subjecting the object to an imaging sequence, —acquiring MR signal profiles in a Cartesian k-space sampling scheme, wherein each MR signal profile is acquired in the presence of a temporally constant magnetic field gradient along a readout direction and a sinusoidally modulated magnetic field gradient along a phase encoding direction, and—reconstructing an MR image from the acquired MR signal profiles taking the modulation scheme of the magnetic field gradients into account. The invention proposes that the frequency of the sinusoidal modulation of the magnetic field gradient is varied during acquisition of each MR signal profile. 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.
