    Abstract: A radiographic apparatus includes a gantry and a table supporting a patient and having a device that immobilizes the head of the patient lying on the table. Such device includes a dome configured to support the head of the patient; a basal plate; one or more junctions provided at a first end of the basal plate; two uprights provided at a second end of the basal plate opposed to the first end, two slits being defined in the two uprights, a slide being disposed within each slit; and a cursor sliding in the two slits and configured to be blocked in position by a bushing, wherein the basal plate, the one or more junctions, the two uprights, the cursor, and the bushing are all radio-transparent and non-metallic.

    Abstract: An imaging apparatus includes a patient table with a gurney and a base. The gurney can slide between two extreme positions, an electrically supplied motoreducer controlled by a control unit causing the table to slide and having a lock/unlock system of the sliding that is mechanical, independent from the electrical supply, and manually controlled by a grabbing organ actuated by a human operator. The patient table may be provided together with a gantry having a housing transparent to light for at least part of its extension, and a control unit of the radiographic apparatus. The housing or a part thereof is associated with a source of light, and the control unit, when the apparatus is electrically supplied, and/or other status conditions are determined by a status sensor, causes the light source to be illuminated and the housing to light up in its translucent parts signalling the status condition.

    Abstract: 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.
