Tooth identification in digital X-ray images and assignment of information to digital X-ray images
First Claim
1. A method of identifying at least one object, including teeth, in a digitized X-ray image, comprising, specifying the areas depicting the object, using image-processing algorithms, by one of segmenting and edge detection of the X-ray image, and that these areas are, for further specification of said areas linking, linked by computation to those image parameters of the X-ray apparatus which are used for making the X-ray image.

Abstract
A method and device for identifying objects, especially teeth, on a digitized X-ray picture, by using image processing algorithms to localize areas containing the object by segmenting and/or edge detection, these areas being computationally linked with parameters of the X-ray unit and, optionally, with patient-heightened specific parameters. Another method and device for assigning information to objects, especially teeth, determined in a digitized X-ray picture or in a schematic representation, includes a first step detecting the digitized X-ray image for the schematic representation, a second step in which a determination of objects manually or automatically ensues in the event these objects have not yet been determined, a third step selecting the object for which additional information should be stored, retrieved or deleted, and a fourth step in which a reference tht is stored is followed for a query operation to determine the information displayed by using such reference.

11. A system for the identification of objects, including teeth, in a digitized X-ray image, comprising
an input and output device for interactive control of the system, and a processing unit which has access to the digitized X-ray image and has access to apparatus-specific information concerning the X-ray apparatus and which delimits the objects in the digitized X-ray image on the basis of said information and also by one of segmentation and edge detection.
