    摘要: In an x-ray detector of the type employing a gas-filled chamber containing a number of electrode plates for detecting ionization event caused by the interaction of x-ray photons with the gas, a number of detector cells are formed, each detector cell containing two electrode plates disposed in a plane in succession in the direction of propagation of an incoming x-ray beam. In order to permit the acquisition of different spectral ranges, the electrical signals from the electrode plates are respectively conducted out of the chamber. The electrode plates are plugged into spring contacts and are connected group-by-group to a conductor foil. Each conductor run within the conductor foil has a contact projection for making electrical contact between the conductor foil and a printed circuit board, which carries electronic components for processing the detector singles.

    摘要: An apparatus is provided for producing metallic heat exchanger tubes having a heat exchange surface that is increased by fins. A rotating tube has helically wound on its outer surface a strip that forms the fins, with this strip being fed to the tube surface under tension, and with the bottom edge of the strip being welded to the tube. The contact surface that exists between the tube and the bottom edge of the strip, and that extends helically on the surface of the tube, is fused exclusively at the surface of the tube with a laser beam that is directed in the region where the strip runs onto the surface of the tube, and that fuses a portion of the tube surface that in the axial direction of the tube corresponds at least to the width of the bottom edge of the strip and in the circumferential direction corresponds approximately to the same amount. At the same time, the laser beam fuses the bottom edge of the incoming strip in the region where the strip runs onto the surface of the tube. The fused surface areas are joined in a gap-free manner as the strip runs onto the tube, and are connected to one another to form a continuous, residual-gap-free welding.

    摘要: A cooling system for relatively movable components, such as a rotor seated for rotation with respect to a stationary component, includes a sealed channel in the stationary component disposed between the stationary component and the movable component, and an evaporator disposed within the sealed channel. The channel is filled with coolant, such as alcohol or oil, which is circulated by a pump in a closed circulation path. Heat is thereby conveyed from the system components to be cooled to the evaporator, and from the evaporator to a location where the heat can be dissipated without disturbing operation of the device. The cooling system is suitable for use, for example, in a computer tomograph for cooling the radiation detector.

    摘要: In an exemplary embodiment, a measuring arrangement for irradiating the examination subject from different directions has a radiation source, a radiation receiver, and a computer connected to the radiation receiver for computing the attenuation values of specific image points of the irradiated body layer from the output signals of the radiation receiver. A collimator is present with a collimator grid compartment for each detector of the radiation receiver. Every detector is comprised of a scintillator crystal and a photoelectric transducer. The scintillator crystal is mounted on the surface of the photoelectric transducer such that the transducer is disposed between the associated collimator plate and the scintillator crystal. The scintillator crystal is coated, on its surface, with the exception of the surface confronting the photoelectric transducer, with an optical seal which can be light-reflecting on its side resting against the scintillator crystal.

    摘要: A computer tomograph with a fan-shaped x-ray beam and two detector arrays. The two detector arrays are arranged in parallel and adjacent one another. Their lengths are dimensioned such that one detector array is suited for the head region, and the second, for the trunk (or body) region of the patient. The numbers of detectors of the detector arrays are equal, such that the division of the shorter detector array is finer than that of the longer one. There are connected, in parallel, to the input of the measured value converter two mutually corresponding detectors of the respective arrays. For each detector row, there is one light- and airproof chamber provided, and disposed between the two chambers and the two collimators there is a partition made of radiation-absorbing material.

    摘要: The invention relates to a ball-and-socket implant (I), in particular an acetabular implant, preferably in the shape of a spherical cup shell, said implant having at least one region with a surface structure (2, 7). The at least one region extends between the equator and the pole of the spherical cup shell. The surface structure comprises a plurality of structural elements (6), each of which is formed by a plurality of intersecting ridges (3, 8) with opposite inclinations. The number of structural elements (6) on the equator (5) or on a circle of latitude near the equator is the same as on a circle of latitude near the pole. The ridges (3, 8) have a curvature such that the inclination of the ridges with respect to the circles of latitude, and thus an angle between a tangent of the ridge curvature and a circle of latitude, continuously increases from the equator (5) to the pole (4).
