Abstract
A cephalostat for acquiring teleradiographic images through an extraoral radiographic apparatus includes a pair of earpieces at the ends of two shafts and a small bar for resting again the nasion, these components being manually adjustable to adjust them to the skull of the patient under examination, wherein the cephalostat is free from metallic elements in the parts on which X-rays impinge, with the exception of radio-opaque markers, and is interchangeable with a craniostat fixed in the same apparatus seat.
Claims10
A cephalostat for acquiring teleradiographic images comprising:
- an extraoral radiographic apparatus;
- and
- a plurality of components comprising,
- a supporting element for a pair of earpieces provided at ends of two shafts;
- and
- a bar for resting again a nasion,
- wherein said components are manually adjustable in relation to a skull of a patient under examination, said components falling at least partially inside a path of an imaging x-ray beam,
- wherein said cephalostat is free from metallic parts at least in parts of said components falling inside the X-ray beams path, with exception of radio-opaque markers, and
- wherein said cephalostat is interchangeable with a craniostat fixed in a same apparatus seat,
- further comprising a base from which a plurality of pins protrude, thereby enabling a removable fixing of the based to a column of extraoral radiographic apparatus.
A cephalostat for acquiring teleradiographic images comprising:
- an extraoral radiographic apparatus;
- and
- a plurality of components comprising,
- a supporting element for a pair of earpieces provided at ends of two shafts;
- and
- a bar for resting again a nasion,
- wherein said components are manually adjustable in relation to a skull of a patient under examination, said components falling at least partially inside a path of an imaging x-ray beam,
- wherein said cephalostat is free from metallic parts at least in parts of said components falling inside the X-ray beams path, with exception of radio-opaque markers, and
- wherein said cephalostat is interchangeable with a craniostat fixed in a same apparatus seat,
- further comprising a radio-transparent mechanism moving the earpiece shafts,
- wherein said radio-transparent mechanism has friction devices for manually moving said components.
A method of positioning a patient making use of a cephalostat for acquiring teleradiographic images comprising:
- an extraoral radiographic apparatus;
- and
- a plurality of components comprising,
- a supporting element for a pair of earpieces provided at ends of two shafts;
- and
- a bar for resting again a nasion,
- wherein said components are manually adjustable in relation to a skull of a patient under examination, said components falling at least partially inside a path of an imaging x-ray beam,
- wherein said cephalostat is free from metallic parts at least in parts of said components falling inside the X-ray beams path, with exception of radio-opaque markers,
- wherein said cephalostat is interchangeable with a craniostat fixed in a same apparatus seat, and
- wherein two radio-opaque markers are fixed on the pair of earpieces, and wherein a radio-opaque marker is fixed at the end of the bar in contact with nasion,
- the method comprising:
- verifying a correct positioning of the patient through presence of laser rays tracking lines on the patient's face and of radio-opaque markers, thereby enabling a verification of correct positioning on scout radiographies.
