ABSTRACT:
The invention relates to a method for imaging a desired object by using a panoramic X-ray radiography apparatus equipped with exposure automatics, the apparatus including an X-ray generator (5), an X-ray tube (6), and an image receptor (8) with its holder (10). The detecting of the cone of rays (7) which has passed through the object, for the purpose of determining the exposure value, is carried out during the imaging at points positioned in each given case at different heights (17) in the cone of rays, by using one or more detectors (1). The positioning can be done either by moving the detector or by activating a certain detector in an arrangement of a number of detectors.
