Abstract: An X-ray emitter, particularly a dental X-ray apparatus, includes an X-ray source disposed in a housing, wherein the interior housing has an emission aperture and a diaphragm is provided which delimits the X-rays leaving the emission aperture to form a X-ray fan beam and is disposed at a distance from said emission aperture. In the space between the emission aperture and the diaphragm there are disposed radio-transparent means for deflecting light waves in the visible range, and in or on said housing there is provided an image detection system for the deflected light waves.

Abstract: A dental X-ray system includes a radiation source used to produce X-rays and disposed in an X-ray head. The system has an electronic sensor used to detect X-rays. The sensor can be detachably connected to a central unit of the X-ray system by a plug-in connection. The electronic control system for the sensor is integrated into a plug connected thereto by an external connection cable and is associated with the sensor, thereby enabling a simple exchange between two sensors. The system can include several sensors that can be operated parallel to each other.

Abstract: An X-ray apparatus, in particular a dental X-ray apparatus, includes an X-ray radiation source for generating X-ray radiation to be directed at an object to be investigated, for example, a patient's tooth or jaw. The apparatus has an optical device through which an aiming device, for example, an additional visible pilot radiation generated by a further light source, is directed substantially parallel to the X-ray radiation at the object to be investigated to facilitate the positioning of the X-ray head.

Abstract: The invention relates to an X-ray sensitive camera (1, 55) comprising a first X-ray sensitive image receiver (4), for creating a first tomogram with a first depth of field profile, in addition to a second X-ray sensitive image receiver (5) for creating a second tomogram with a second depth of field profile. The invention also relates to an X-ray device comprising an image receiver (4, 5) that is contained in an X-ray sensitive camera (55), in addition to an X-ray emitter (52) with a primary diaphragm (57) and adjusting means (43, 44) for the image receiver and/or X-ray emitter and/or primary diaphragm and/or a combination thereof. The camera is equipped with a second image receiver (5), which can be brought into the beam path (54) of the X-ray emitter using the adjusting means (43, 44).

Abstract: A method is proposed for compensating for the dark current of an electronic sensor having a plurality of pixels with an individual dark-current response, radiation for producing an image signal (BS) being directed from a beam source (3) onto a detector arrangement (4) containing the sensor, and a recording being taken with different clock-out rate (v) (integration time) by reading the detector signal (S) present in the pixels of the sensor, in which, before the beginning or after the end of the recording with radiation, the sensor is read out without radiation with at least two different clock-out rates (v1, v2) and at least two dark-current signals (DC1, DC2) are thereby picked up for each pixel, in which the dark-current signals (DC1, DC2) that have been read out are then used to calculate a dark-current value (DV) of individual pixels of the sensor as a function of the clock-out rate (v), and in which a correction is then made, using the dark-current value associated with each pixel, to the detector signal

Abstract: A sensor that can be placed intraorally in the mouth of a patient for the production of tooth/jaw exposures of a patient has a narrow housing, approximately rectangular in a top view, for an image detector and a control circuit board to which lines are connected, which can be connected, with a free end, with an image processing unit via a connecting cable exiting from the housing at the back wall of the housing. At least one narrow side of the housing has a rounded shape that is adapted to the anatomical characteristics of the upper jaw of an average patient.

Abstract: In a method and an apparatus for producing X-ray tomograms of the jaw and skull of a patient, a detector arrangement having at least one x-ray detector is provided. The radiation-sensitive area of the detector is a sub-area of the total detector area required for the subject exposure. The image exposure ensues in a number of chronologically separate sections in which, following a first sub-exposure, the detector arrangement is displaced along the longitudinal axis and/or the transverse axis of the detector surface and the diaphragm aperture of the primary diaphragm associated with the x-ray source is simultaneously correspondingly adapted so that the position of the x-ray beam is shifted so that it still strikes the detector appropriately after the detector is displaced.
