Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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…
