Abstract

A method of magnetic resolution (MR) imaging of a moving portion of a body of a patient placed in an examination volume of a MR device. For the purpose of enabling improved interventional MR imaging from acquiring a MR signal data with motion compensation, the invention proposes that the method includes repeated acts of collecting tracking data from an interventional instrument introduced into the portion of the body, subjecting the portion of the body to an imaging sequence for acquiring one or more MR signals therefrom, wherein parameters of the imaging sequence are adjusted on the basis of the tracking data, and reconstructing one or more MR images from the MR signal data set.
