    摘要: The invention relates to a system for determining a sensor holder for holding an object, whereby the sensor holder carries a digital sensor of a dental X-ray unit. The inventive system comprises an input and display unit for interactively controlling the same, whereby a schema image can be displayed on the display unit. The system also comprises a processing unit that, based on the selected sensor holder, simulatively generates the schema image from which is apparent which area of the object is displayed when using the selected sensor holder.

    摘要: 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.

    摘要: In a dental x-ray diagnostics installation that includes an x-ray radiator, an image detector arranged diametrically relative thereto a CCD following the subject to be transirradiated in radiation direction, control electronics with a control part for driving the image detector, an image processing unit that edits the signals acquired from the image detector, and an operating device with which the x-ray radiator can be switched on and off, the image detector is continuously read out with a clock generator and the incoming data read from the detector are constantly subjected to a threshold check. The image detector is operated in a read-out mode when the x-ray radiator is switched off and is switched into an exposure mode given the presence of radiation and the upward transgression of a defined threshold, and vice versa.
