Abstract

The invention relates to a method for cephalometric imaging using an apparatus (1) which comprises an X-ray source (5), a line detector camera (8) equipped with a digital detector, which line detector camera is located to a position far away from the X-ray source (5) for carrying out cephalometric imaging while the slot of the line detector camera is substantially vertical. In cephalometric imaging, an X-ray beam (11) located substantially on the vertical plane is directed from the X-ray source (5) through the object being imaged, and the X-ray source (5) is at the same time turned about the rotation center (13) located between the X-ray source and the line detector camera (8) in order to scan the object being imaged in the horizontal direction, whereby the line detector camera (8) is moved during the scanning movement in such a way that the ray beam (11) meets the slot (14) of the line detector camera. In the method, the effective focal spot is transferred from the rotation center (13) to the focal spot of the X-ray source (5) by transferring the rotation center by means of a transverse linear movement (A) with respect to the ray beam (11).
