A method and apparatus for acquiring a radiographic image of a patient includes using an X-ray source and at least a X-ray detector supported in opposed positions, the area under investigation being positioned between the X-ray source and detector in the propagation bundle of the radiation emitted by the X-ray source, the X-ray source and detector being movable along a pre-set trajectory due to at least two movements. The X-ray dose administered to a patient can be adjusted automatically, dispensing the minimum dose necessary to achieve a radiographic image of good quality. The method and apparatus provide for performing a scout acquisition, preceding the acquisition of a real panoramic image, in a particularly efficient way. During the scout acquisition, data are collected for adjusting the X-ray dose for the following radiographic image acquisition.

Method and apparatus for adjusting technical exposure factors during radiographic acquisition

Head support

A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by two rods. The upper portion includes a rest for a patient's forehead, wherein the rest for the patient's forehead rest has an arched shape vertically sliding in a suitable seat inside a crossbeam supported by the rods. A method of use of a craniostat according to the invention is also described.

Craniostat for acquiring extraoral dental radiographies

A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by rods. The upper portion includes a crossbeam and rests for a patient's temples, the rests being formed by two arches articulated with the crossbeam. The arches lean on the patient's temples, and are blocked by a control system, which, in one embodiment, is configured as oscillating levers. The blocking action is caused by shape friction generated at the time of activation via the control levers. A method of use of a craniostat is also described.

A craniostat for an extraoral dental radiographic apparatus includes a chin rest and a bite, which are optionally removable. The bite has centering surfaces of pre-defined orientation with respect to a centering position of the bite and is blocked in a blocking position by tightening the centering surfaces against tightening surfaces also having a pre-defined orientation with respect to the bite centering position, so that in tightened condition the bite is also automatically brought in correct centering position on the sagittal plane. A method of use of a craniostat is also described.
