| 摘要 |
The invention relates to a method for imaging the head area by using a line detector camera (8) equipped with a digital detector, at which camera is directed an X-ray beam (11) through the object being imaged. In the method is used an apparatus (1) which makes possible the implementation of cephalometric imaging and at least one other imaging method, such as panoramic imaging. The apparatus comprises an X-ray source (5), a primary collimator (6) in conjunction with the X-ray source, a line detector camera (8), which is located to a position further away from the X-ray source (5) for implementing cephalometric imaging and/or to a position closer to the said X-ray source for the said other imaging method, and a secondary collimator (9) in the vicinity of the line detector camera (8) intended for cephalometric imaging. In the method, the radiation emitted from the X-ray source (5) is collimated in cephalometric imaging without turning the X-ray source in such a way that the ray beam (11) bypasses the position of the line detector camera (8) closer to the X-ray source (5).
