Abstract: Disclosed is a method and a device enabling x-rax pictures for tomosynthesis to be produced by means of an x-ray examination unit. The method consists in generating radiated pulses from various directions during the radiation detection of an object (3), selecting during the radiation break such signals which can be deflected by a radiation receiver intended for a solid body (2); supplying such signals to a computing and control device (4) and calculating at least one positron emission tomography of at least one predetermined layer.

Abstract: A radiation diagnostic installation includes a panorama scanner for tomographically scanning a subject with radiation and for generating electrical signals dependent on the radiation shadow of the subject. A signal processor includes a memory for storing the electrical signals during the tomographic scanning and a computer for calculating signals corresponding to a tomogram of the subject in a desired slice position. The computer determines the desired slice position from the calculation of individual slice positions and their evaluation, thereby enabling faster production of tomograms in a desired slice position.

Abstract: In a method for acceptance and stability testing of filmless dental radiographic equipment a test measurement body having a plurality of absorption elements which absorb differently is arranged in the beam path of the X-rays at a defined close distance from a radiation-sensitive sensor. The electric signals obtained from the sensor are fed to a computing unit which processes these to form image value signals which are then fed either directly to a display unit or are firstly compared with prescribed desired image values and, in the case of deviations, fed to the display unit. The test measurement body includes a holder for reproducibly holding a sensor which can be applied intraorally to a patient.
