A medical examination or treatment facility is proposed. The medical examination or treatment facility, which is a magnetic resonance facility in particular, comprises a main unit and a support structure that can be fastened to the main unit, the support structure being a profile frame structure. Because of their particular form profile frames allow a wide range of components to be fastened without major outlay. They are simple, stable and flexible to use and allow a significant cost reduction compared with conventional steel structures. The profiles in the profile frames allow changes to be made easily to the arrangement of fastened parts at any time by moving fastening units in the profile frames.
