Dental X-ray device with imaging unit for surface detection and method for generating a radiograph of a patient

摘要

The invention relates to a dental X-ray system for the creation of a radiograph (13), comprising an imaging unit (5) for surface detection. The imaging unit (5) has a light source (6), which produces a polychromatic beam of visible light (6′), a masking edge (7), which extends at least partially into the polychromatic beam of light (6′) between the light source (6) and the recording area (19) for the purpose of creating a shadow demarcation line (17) in said recording area (19), and an optical detector (8), wherein the light source (6), the masking edge (7) and the optical detector (8) are mounted directly on the supporting device (2) and/or on the X-ray source (3) and/or on the X-ray detector (4) and can be moved together therewith past the recording area (19) in circular motion.

主权项

1. A dental X-ray system, comprising:
an X-ray source; an X-ray detector; a supporting device adapted to move the X-ray source and the X-ray detector at least partially around a recording area located between the X-ray source and the X-ray detector; and at least one imaging unit adapted to image the recording area, wherein the at least one imaging unit comprises:
at least one light source adapted to produce a polychromatic bundle of light directed toward the recording area,at least one masking edge that extends, at least partially, into the polychromatic bundle of light between the light source and the recording area for creation of a light-colored region, a dark-colored region, and a shadow demarcation line separating the light-colored region and the dark-colored region in the recording area, andat least one optical detector adapted to image the light-colored region, the dark-colored region, and the shadow demarcation line, wherein the at least one light source, the at least one masking edge, and the at least one optical detector are disposed on at least one of the supporting device, the X-ray source, and the X-ray detector and can be moved, together with the X-ray source and the X-ray detector, around the recording area.
