    • An adjusting and holding assembly for magnet coils in a nuclear spin tomography system includes mechanical adjusting devices connected to a frame structure for the mutual alignment of the connected to a frame structure for the mutual alignment of the base field magnet coils. In order to enable a relatively simple adjustment of the individual magnet coils to produce a highly homogeneous base field, at least one of the magnet coils is rigidly connected to the frame structure, while each adjustable or positionable magnet coil is held at three points via at least one support device and three adjusting devices within the frame structure. Each support device comprises a support element in the form of a spherical sector rotatably mounted to a respective coil and slidably resting on a horizontal support surface of the frame structure. The support points of the adjustable magnet coils are longitudinally spaced from the center of gravity line of the respective magnet coil so that an additional tilting force is brought about.

    • A frame structure for supporting individual magnetic coils forming a magnet system used in nuclear spin tomography comprises several frame parts made from a ferromagnetic material to provide relatively simple magnetic shielding. The individual magnetic coils are concentrically aligned one behind the other along a common axis to form the magnet system. Several elongate beam, rod, or plate-shaped magnetic shielding elements extend parallel to the common axis and are evenly distributed in the circumferential direction around the magnet system thus forming a generally cylindrical surface. End-plate magnetic shielding parts having a central opening of predetermined radius are provided at the end faces of the cylindrical surface formed by the shielding elements to create a cage-like frame structure. Coil receiving elements can be used to rigidly connect the axis-parallel shielding elements with the individual magnetic coils.

    • A magnetic suspension bearing for a rotating body having at least two magnet systems of coaxial permanent magnets arranged sequentially along the axis of rotation of the rotating body. Each magnet system is provided with two permanent magnets disposed on the rotating body and a stator, respectively. Each such permanent magnet is magnetized in a direction perpendicular to a major external surface, the adjacent surfaces of the magnets within a magnet system being of like polarity so as to repel one another. Each of the magnets is constructed so as to form a truncated cone, the axis of which coincides with an axis of rotation of the rotating body. In one embodiment, the apex of the cones are directed towards one another. The apex angle of the cones is advantageously preselected to provide desired axial and orthogonal components of force.

    • In an arrangement for preparing a sectional image of the body, the picture elements of which are derived from the absorption of ionizing rays, the detector system contains detectors associated with a cooling system having a cooling finger against which the cooling surfaces of the detectors rest and which is connected via a cryogenic line to two coolant tanks which are arranged in the plane of motion of the detector system centrally symmetric to the center of rotation. As a result the rotating detector system with the coolant supply requires no automatic mass equalization device adapted to the consumption of coolant, and the cooling system can be designed for different operating times.
