Abstract
A magnetic resonance device (1) for imaging inter alia human organs by way of magnetic resonance is provided in close proximity with an x-ray imaging device (20). When, for example, in neurosurgery interventional techniques are executed in combination with a magnetic resonance device (1), the organs are suitably visualized but the instruments guided to an organ via an opening in the body are not visible or only hardly so. Prior to the present invention, in order to carry out interventional procedures, the patient would be transported between a room housing magnetic resonance device and a room housing on x-ray device. Transporting the patient over a long distance between two rooms is objectional because of the risk of motion of the instruments lodged within the body of the patient; as such motion could be fatal to the patient. A solution consists in arranging an X-ray device (20) adjacent the MR device (1), so that the patient need be transported a short distance only. Undesirable mutual influencing of the MR device (1) and the X-ray device (20) is counteracted by shielding the static magnetic field of the MR device and the electromagnetic fields generated by the X-ray device.
