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.

Method for imaging an object by means of a panoramic apparatus equipped

The invention relates to a mammography device, having a frame column (3) comprising a slide (2) mounted vertically (Z) slidingly onto bearings, into the horizontal axis of which the photography head (1) is pivotally mounted onto bearings. According to the invention, the control device (10), the photography head (1) being tilted, guides the hoisting mechanism (M1) of the slide (2) according to a preset program and to the observed angle of inclination (.OMEGA.) in such a way that the center point of the support plate (6) in the photography head is at essentially the same height above the support (20) at the end of the tilting movement.
