ABSTRACT:
An imaging system includes to a magnetic resonance device (1) for imaging inter alia human organs by way of magnetic resonance and an X-ray device for imaging by way of X-ray. When interventional techniques are applied 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. These instruments must be imaged by means of an X-ray device (20); the patient must then be transported some distance, for example a few meters, in order to obtain distortion-free images of the instruments. Transporting the patient has some drawbacks. There is a risk of motion of the instruments within the patient and, moreover, the coordinate systems of the MR device (1) and the X-ray device (20) might deviate from one another. A solution consists in arranging the X-ray device (20) immediately adjacent to or in the MR device (1), so that the patient need not be transported at all or only over a small distance. The undesired mutual influencing of the MR device (1) and the X-ray device (20) is counteracted, for example by using a solid-state X-ray detector (22) which includes a solid-state image pick-up device and, for example by making the position of the X-ray tube (40) dependent on the static magnetic field of the magnetic resonance device.
