    摘要: An X-ray diagnostic system for angiographic X-ray examinations having an X-ray source for irradiating a patient, a television image intensification chain, and an image subtraction device for producing images which are the result of the difference between images taken at a progression of discrete times during which the concentration of an X-ray contrast medium in blood vessels changes. The subtraction device is provided with two image memories. A control device having a preprogrammable memory controls the times at which image data are stored in the image memories. The preprogrammable memory may be programmed for each time of image storage, or may be programmed only for the times of storage in the first image memory and a time delay factor for storage in the second image memory relative to the times of storage in the first image memory. The time delay factor may be constant or variable.

    摘要: In an illustrated embodiment a plurality of x-ray sources are arranged at equal angles about a rotating frame. Each source and detector arrangement may provide the desired number of measurements such as 240, so that the required angular movement for scanning is reduced by a factor corresponding to the number of sources. In one embodiment with three sources and 240 detectors for each source, the desired number of measured values may be obtained by rotation through 120 degrees instead of 360 degrees. In another illustrative embodiment, the narrow beam from the x-ray source covers about 30 detectors, the beam and detectors being linearly scanned so as to generate about 240 measurements, there being three source-detector arrangements separated by 60 degrees, so that scanning is carried out by rotation through 60 degrees rather than 180 degrees.

    摘要: An operating handle for an encapsulated switching apparatus which includes a housing having a door and a stationary switching shaft. The handle is fastened to the door of the housing in a switched-on position of the apparatus by means of a spring-loaded shiftable locking plate which is shifted against the force of a loading spring in a switched-off position of the apparatus into a position in engagement with a stop member for releasing the switching shaft from the locking plate. The improvement comprises the stop member being formed by a resilient detent spring disposed within the operating handle, the restraining force of which can be overcome by an operating force applied to the handle.
