ABSTRACT:
A method and apparatus for visualizing an interventional device in a body using a magnetic resonance (MR) imager. In operation an MR pulse sequence is applied to the body so as to develop MR signals, which are processed so as to acquire one or more images. An operator of the imager uses a hands-free device to control parameters of the applied pulse sequence so as to cause the images to show an intensity distortion artifact in the area of the interventional device that is increased as compared to intensity distortion artifact in conventional MR images; and, after an image distortion which is expected to be produced by the interventional device is seen, the operator changes the applied pulse sequence parameters, in a “hands-free” manner, so that said one or more acquired images show an intensity distortion artifact in the area of the interventional device that is reduced as compared to said increased intensity distortion.
