ABSTRACT:
In a magnetic resonance apparatus having vertically spaced pole shoes with an examination space therebetween and with an illumination system for illuminating at least a part of an examination space, the illumination system includes a light source arranged outside the examination space and a lightguide having a first end optically coupled to the light source. The lightguide extends above the examination space up to a symmetry line of the examination space. Deflection optics are optically coupled to a second end of the lightguide that lies opposite the light source. The deflection optics deflects the light rays emerging from the second end downwardly in a vertical direction. The lightguide is formed by a bundle of optical fibers which are arranged side-by-side in a flat arrangement on the upper pole shoe so as to reduce the height of the examination space only insignificantly.
