Device for bildaufnahmne by means of x-rays in the dental field.

摘要

A device (1) for image recording in the dental field by means of x-rays comprises a pivot means (3) for pivoting of an arm (2), one of the x-ray beam source (11) and a mapping means (12) for the x-ray beam, a carriage (4) to the linear movement of the imaging agent for the x-ray beam (l). The apparatus (1) to the image recording by means of x-rays in the dental sector receives a first set of projizerter images, which extend over a first region and a second set of projizerter images, which extend over a second region of the fact that the imaging means for the x-ray beam (12) to a first detection position (p1) is moved and the first set projizerter images with the second set of projizerter images are added together.A detection means for the original position (5) for detecting a starting position of the imaging agent for the x-ray beam (12) includes an optical sensor (52), a position of one end (51a) of a shield plate (51) for light is detected, the linearly, together with the imaging means for the x-ray beam (12) for the x-ray beam is moved and sensor detects a point in time at which the end (51a) of the shield plate for light of the optical sensor (52) in the forward direction, as the original position. In accordance with this arrangement, it is possible for extremely precise images and at the same time a large image window with the use of the imaging agent (12) for the x-ray beam which has a small image pick-up surface (12a) has, in order to achieve.
