Embodiment Construction

[0041] figure 1 A diagnostic system 10 according to the invention for examining the cranio-maxillofacial region of a patient is shown. The diagnostic system 10 includes a panoramic x-ray machine 14 and a device 16 for editing panoramic radiographic images generated by the panoramic x-ray machine 14 . In particular, a panoramic x-ray machine 14 (panoramic dental x-ray machine) for dental diagnosis is shown.

[0042] In the exemplary embodiment shown, the patient's head is examined as examination object 12 . An x-ray source 18 movable around the examination object 12 emits x-ray radiation which penetrates the examination object 12 and is received by an x-ray detector 20 . The X-ray source 18 and the X-ray detector 20 are fixedly connected via corresponding rotatable arcs 22 (also called arms). Typically, the arc 22 is rotatably or rotatably mounted in a position above the object of examination 12 . The X-ray source 18 and the X-ray detector 20 travel around the inspection ob...

Abstract

The present invention relates to a device (16) for editing a panoramic radiography image (24) of an examination object (12) generated by a panoramic X-ray machine (14), comprising: an input interface (36) for receiving the panoramic radiography image as well as reconstruction data of the panoramic radiography image, the reconstruction data including information on a course of projection lines (28) of the panoramic radiography image between an X-ray source (18) and an X-ray detector (20) of the panoramic X-ray machine as well as information on an image surface (30) of the panoramic radiography image; an evaluation unit (38) for evaluating the reconstruction data and for determining an image section (46) of the panoramic radiography image that has been generated on the basis of one of the projection lines with two intersection points (32, 34) with the image surface; an image editing unit (40) for editing the panoramic radiography image based on the determined image section; and an output unit (42) for outputting the edited panoramic radiography image. Moreover, the invention relates to a method for editing a panoramic radiography image (24) of an examination object (12) generated by a panoramic X-ray machine (14) as well as a diagnosis system for examining a craniomaxillofacial area of a patient.

Description

technical field [0001] The present invention relates to a device and method for editing a panoramic radiographic image of an inspection object generated by a panoramic X-ray machine. Furthermore, the invention relates to a diagnostic system for examining the craniomaxillofacial region of a patient. Background technique [0002] X-ray examinations have been a widely used standard procedure for many years, especially in medicine, but also in industry, among other applications. X-rays are absorbed differently in structures with different thicknesses within the examination object, so that images of internal structures can be generated. In medical diagnosis, the inside of the human body can be examined. [0003] In this respect, a single X-ray image can be generated, several images taken from different angles can be composited into a panoramic image (panoramic X-ray machine), or can be reconstructed from spatially different projections (Tomography or X-ray computed tomography) ...
