摘要:
A dental x-ray diagnostic installation for the production of panoramic exposures of slices of the skull of the patient particularly in the region of the jaw, characterized by an exposure unit with an x-ray unit pivotable around an axis and displaceable in a plane perpendicular to the axis, a film holder unit lying opposite and moveable relative to the x-ray unit, a head holder arranged between the two units, a control arrangement for controlling the pivoting and displacement movement of the exposure unit relative to the head holder and also controlling the movement of the film holder relative to the x-ray tube of the exposure means and an input arrangement for inputting information of the selected curvature of the slice being exposed. The improvements are that the input means is constructed so that the curvature of the slice to be exposed can be directly graphically inputted into the control arrangement such as by means of a monitor with a light pen or by means of a "computer graphic tablet".
