Abstract
The invention relates to a method of MR imaging of an object (). It is an object of the invention to enable MR imaging using a 3D radial or spiral acquisition scheme providing an enhanced image quality in the presence of motion. The method comprises the steps of: —generating MR signals by subjecting the object () to an imaging sequence comprising RF pulses and switched magnetic field gradients; —acquiring the MR signals using a 3D radial or spiral acquisition scheme with oversampling of a central portion () of k-space; —detecting motion-induced displacements (d) and/or deformations of the object () during the acquisition of the MR signals and assigning each of the acquired MR signals to a motion state; —reconstructing an MR image from the MR signals weighted in the central portion () of k-space, wherein a stronger weighting (W,) is applied to MR signals acquired in more frequent motion states, while a weaker weighting (W,) is applied to MR signals acquired in less frequent motion states. Moreover, the invention relates to a MR device () and to a computer program for a MR device ().
