The device further includes: a measurement unit for measuring features related to the x-rays used for exposing at least part of the patient, the measurement unit being arranged between the x-ray source and the patient; and a second communication means for transmitting the x-ray exposure data which includes the measured features to the x-ray data management unit.

Measurement and data communication device for an intraoral dental radiology system

A method for generating a panoramic layer image of an object to be imaged, by employing a 2D panoramic X-ray device, the object being imaged by projecting X-rays generated by an X-ray source through the object in a projection direction and recording the X-rays with an X-ray detector. Several 2D X-ray projection images are continuously recorded from various imaging directions while the X-ray source and the X-ray detector move around the object. At least one panoramic layer image is calculated from the recorded 2D X-ray projection images using a reconstruction method. The panoramic layer image is calculated by selecting and employing at least one partial area from at least two 2D X-ray projection images in relation to an active sensor area.

Read-out and storage electronicsincluding a microcontrollerand a data storage deviceare provided on or in the housing, and at least one period of operation of the X-ray tubecan be acquired and stored in the data storage deviceby means of the read-out and storage electronics

X-ray emitter

A small dental X-ray apparatus has an X-ray emitterfixed to a cantilever, which X-ray emittercan be manually adjusted in space relatively to a basic position by means of the cantilever. Meansare provided for the acquisition of the position and alignment of said X-ray emitter () in space. The method serves to automatically detect deviation of an actual position in space from a target position in space, which deviation is indicated by signalling elementsand the operator is informed on the quality of the actual position and on the direction of a change in the actual position which may be required to acquire an improved position.

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.
