Abstract: A gas detector for x-rays can be easily taken apart for repair and service. The gas detector has plate-shaped electrodes which are plugged into spring contacts, the spring contacts being connected in groups to a conductor foil which is connected by means of contact projections to a printed circuit board. The printed circuit board carries electronic components for processing detector signals from the electrodes.

Abstract: 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.

Abstract: An intracavitary ultrasound probe, for producing a number of tomograms of an examination region with a common origin, includes a section adapted for introduction into a body cavity, the section having a distal end with an endpiece in which a convex transducer array is contained. The endpiece is seated in the introduction section so as to be rotatable exclusively around a single swivelling axis. The single swivelling axis is radially aligned with reference to the transducer array.
