Abstract
An MR system for interventional procedures, includes an MR imaging device and an interventional instrument, for example a catheter. The MR device is arranged to acquire images of a part of an object. The entire catheter can be imaged in an MR image by providing a conductor loop which comprises two non-magnetic conductors which are situated at some distance from one another underneath the surface of the catheter, and extend along substantially the entire length of the catheter. Furthermore, the catheter may be provided with a conductor loop and a coil in a location on the catheter. By separate adjustment of the current flowing through the conductor loop and the coil, it is possible to image the location on the catheter with a contrast which deviates from that of the remainder of the catheter.
