1. A method for imaging the head area of a patient by taking both cephalometric X-ray and photographic images of desired objects to be imaged, said images being converted to digital mode, if necessary, and conveyed in digital mode to a computer, characterized in that the method involves the use of a mechanism ( 1 ) applicable to cephalometric X-ray imaging, comprising an X-ray source ( 5 ) in front of an object to be imaged, an X-radiation receiving element behind the object, and patient positioning implements ( 8 - 10 ), in which method a patient is placed by means of the patient positioning implements ( 8 - 10 ) in a desired imaging position and imaged in the same imaging position in both modes of imaging.
