<p>The radiographic object holder has a compensating body for tomometric laminography. The compensating body made of water equivalent density solid plastic has a central cylindrical recess into which the holder slides which in turn is rigidly coupled to the radiographic couch, the holder is made of a similar plastic and has a water filled elastic tube on its inside to form lock the object i.e. the patient's head. The diameter of the compensating body (6) recess is larger than the outer diameter of the object holder (8, 9) so that a fixing ring (10) of similar plastic with an eccentric recess for the holder slides in and form locks between the parts. This setting ring (10) can be rotated against the parts by elements (27) driven by a servo motor (13).</p> |
