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.

Sensor that can be placed intraorally in the mouth of a patient for the production of tooth/jaw exposures of a patient

A line detector camera suitable for employment in a dental x-ray diagnostics apparatus contains an x-ray-sensitive detector held in a housing, the detector containing a plurality of detector elements that are arranged to form one or more lines, and having contacts connected to control lines that are in turn connected to a connector part. The connector part makes both electrical and mechanical connection in a releasable manner to a correspondingly fashioned holder of the x-ray diagnostics apparatus.

Line detector camera for employment in, particularly, dental x-ray

An x-ray diagnostics installation for producing x-ray exposures of body parts of a patient has a line detector camera arranged diametrically opposite a radiation source, the line detector camera containing an x-ray detector arranged behind a slot-shaped opening, the width of the x-ray detector being matched to the width or length of the body part to be registered. An adjustment system adjusts the line detector camera relative to the body part such that the slot opening is moved along the body part, whereby the fan beam limited by the radiation diaphragm of the radiation source is moved synchronously relative to the camera motion. The line detector camera can be horizontally or vertically arranged.

Intraoral sensor for a dental X-ray apparatus

A dental x-ray diagnostics installation has a rotary unit carrying an x-ray source and a radiation detector disposed behind a secondary diaphragm, the rotary unit rotating around the jaw of a patient to produce panorama tomograph exposures of the patient's jaw. The radiation detector generates electrical signals proportional to the incident radiation intensity. To simplify signal processing, the detector is formed of one or more semiconductor detectors having a scintillation layer which corresponds to the size of the opening in the secondary diaphragm. The voltages acquired by the detector are converted to digital form, and stored in an image memory. A computer calculates a total image from the signals supplied by the detector, and stored in the memory, during a complete exposure. The signals from the image memory are combined to generate a tomogram of a desired slice of the patient's jaw.

Dental x-ray diagnostics installation for producing panorama slice

In order to provide a dental X-ray diagnostic installation for producing panoramic tomograms of the jaw of the patient and to achieve a simple structure with improved image quality, the apparatus includes an adjustment mechanism for the carrier of the radiation source and the film cassette holder to be adjusted in an orbital curve corresponding to the dental arch of the patient. The adjustment arrangement includes first adjustment parts with which the carrier can be rotated around a first vertical axis, and second adjustment elements for moving or swivelling the first axis in an arch transverse relative to the symmetry axis of the subject during the rotary motion. The swivel radius and the amount of excursion of this swivel motion are selected so that the perpendicular transillumination direction through the subject gives a constant distance between the subject and the film during the motion of the rotary unit. To accomplish this, the invention includes two separate embodiments with various modifications.
