Abstract: In a method for the localization of scintillation events in a gamma camera with a number of photomultipliers the output signals of the photomultipliers, in dependence on a release signal, are subjected to a pattern recognition process. In the pattern recognition process the output signals are compared with comparative signal sets which each comprise the expected values of output signals from photomultipliers which would be generated by several comparative scintillation events with at respective origins at known locations. The locations of the multiple scintillation events are then registered as the origins that belong to a comparative signal set which presents the greatest similarity value to the output signals in question.

Abstract: A sweep device for a storage luminescent screen, in which x-ray images are latently stored, includes a drum having an interior on which the storage screen is mounted, a stimulating radiation source which generates a scan beam of stimulating radiation to cause the storage screen to luminesce picture element-by-picture element, and a deflecting mirror disposed in the center of the drum and rotatable relative to the drum to direct the scan beam onto the screen. The deflecting mirror is disposed in the middle of a measuring head, and the drum is shifted relative to the deflecting mirror for line scanning. For acquiring the light emitted by the storage luminescent screen, a curved light conductor is attached to the measuring head. The curve light conductor has a first end face disposed at the circumference of the measuring head which completely surrounds the point of incidence of the scan beam on the storage luminescent screen.

Abstract: A light guide optical device for guidance of light emitted from an original to an optoelectric transducer for converting the read out image of the original into electrical signals where the original is scanned line-by-line, is formed of a light conducting plate having a first linear side directed toward the original and a second side connected at the ends of the first side which is arcuately curved at least in regions. The plate includes a hole for accepting the transducer which receives light emitted from the surface of the plate at the hole.

Abstract: An apparatus for converting image information generated by radiation incident on a storage layer into an electrical signal sequence by scanning the storage layer with a light beam permits a fast and precise conversion of the radiation image information into the electrical signal. This is a accomplished by connecting the scanned point of the storage layer to photodiodes functioning as light transducers via a light conductor in the form of a transparent, strip-shaped plate. The light conductor plate has a major surface adjacent to the storage area, and respective minor surfaces at opposite narrow ends thereof to which the photo diodes are connected. The apparatus can be used in x-ray television technology, such as medical x-ray diagnostics.

Abstract: An apparatus for converting radiation image information carried by a storage layer into a television pulse sequence has a drum with a surface on which the storage layer is disposed, a scanning light beam directed to said surface, the drum and the beam being rotatable relative to one another and axially displaceable for conducting a line scan and a change of line. The light signals thus acquired from said storage layer are supplied on an optical path to a photo-electric transducer. A fast and precise conversion of the radiation image information is achieved with the storage layer on the inside wall of the drum and the scan beam conducted via a deflection mirror disposed in the center of the drum, and with a lightguide for the optical connection between the scan surface of the layer and the transducer.

Abstract: A system is provided for improving frame adjustments of automatic embroidery machines. Groupings of holes are punched in an elongated tape corresponding to binary numbers. The tape is read by an electro-optical reader which converts the information on the tape to electrical pulses which, in turn, control a drive system for causing the embroidery frame to move predetermined discrete distances.

Abstract: A method and apparatus are disclosed for treating a textile article which has raised embroidery on its front side. A plastic sheet is laminated to the back side of the textile article by the application of heat and pressure. Moisture is applied to the front side of the article so that the embroidery which may have been flattened by the lamination process is returned to its original raised condition.

Abstract: In an exemplary embodiment, a flat radiation beam is detected having a common electrode disposed parallel to the beam plane at one side and a common support with a series of individual conductors providing electrodes opposite successive portions of the common electrode and lying in a plane also parallel to the beam plane. The beam may be fan-shaped and the individual electrodes may be aligned with respective ray paths separated by uniform angular increments in the beam plane. The individual conductors and the connection thereof to the exterior of the detector housing may be formed on an insulator which can be folded into a T-shape for leading the supply conductors for alternate individual conductors toward terminals at opposite sides of the chamber.

Abstract: In an exemplary embodiment, a measuring arrangement for irradiating the radiography subject from different directions comprises a radiation source which emits a radiation beam which penetrates the layer to be examined, its dimension perpendicular to the layer plane being equal to the layer thickness, and a radiation receiver supplies electrical output signals which correspond to the radiation intensity measured. A computer calculates, from the output signals, the attenuation values of specific image points of the irradiated body layer. Correction devices are provided in the radiation beam with which the radiation quality (mean energy) of the radiation impinging on the receiver is determined, each preferably comprising several detectors arranged in series in the direction of radiation and separated from one another by a luminescent layer. The output signals of the correction detectors serve to correct for the radiation hardening in the patient.
