Abstract
Abstract An apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth separated from the X-ray generating unit by a soft-tissue facial portion is composed of a substantially X-ray-transparent body adapted to be mounted in the path of the X-rays between the X-ray generating unti and the film element and an illumination source mounted to the body. The body has an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target. The illumination source is positioned to direct at least one beam of light perpendicular to and outwardly from the body face towards the facial feature along the path of the X-rays generated by the generating unit to produce at least one light spot on the facial feature to serve as an orientation means for said X-ray unit. The apparatus may be dimensioned for positioning either within the mouth or affixed to the X-ray generator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
Apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth on a film element, said mouth portion being separated from said X-ray generating unit by a soft-tissue facial portion, comprising a substantially X-ray-transparent body adapted to be mounted in the path of the X-rays within the mouth of the patient and between the X-ray generating unit and the film element, said body having an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target and a portion having a pair of opposed surfaces dimensioned to be gripped by the teeth of the patient, and illumination means mounted to said body for directing at least one beam of light perpendicular to and outwardly form said face towards said facial feature along the path of the X-rays generated by the generating unit to produce at least one light spot on said facial feature to serve as an orientation means for said X-ray unit.
Claim 2
Dependent Claim
179 words
Apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth on a film element, said mouth portion being separated from said X-ray generating unit by a soft-tissue facial portion, comprising a substantially X-ray-transparent body adapted to be mounted in the path of the X-rays within the mouth of the patient and between the X-ray generating unit and the film element, said body having an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target and a portion having a pair of opposed surfaces dimensioned to be gripped by the teeth of the patient, and illumination means mounted to said body for directing at least one beam of light perpendicular to and outwardly form said face towards said facial feature along the path of the X-rays generated by the generating unit to produce at least one light spot on said facial feature to serve as an orientation means for said X-ray unit.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1, further comprising an X-ray film element support mounted to said body.
Claim 4
Dependent Claim
16 words
The apparatus of claim 2, wherein said film element support is formed integrally with said body.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1, wherein said illumination means are operatively connected to a power source located outside the patient's mouth.
Claim 6
Dependent Claim
12 words
The apparatus of claim 4, wherein said power source comprise a battery.
Claim 7
Dependent Claim
160 words
Apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth on a film element, said mouth portion being separated from said X-ray generating unit by a soft-tissue facial portion, comprising a substantially X-ray-transparent body said X-ray generating unit in the path of the X-rays between the X-ray generating unit and the film element, said body having an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target, and illumination means mounted about the periphery of said body on said outwardly-directed face for directing at least one beam of light perpendicular to and outwardly from said face towards said facial feature along the path of the X-ray generated by the generating unit to produce at least one light spot on said facial feature to serve as an orientation means for said X-ray unit.
Claim 8
Dependent Claim
160 words
Apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth on a film element, said mouth portion being separated from said X-ray generating unit by a soft-tissue facial portion, comprising a substantially X-ray-transparent body said X-ray generating unit in the path of the X-rays between the X-ray generating unit and the film element, said body having an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target, and illumination means mounted about the periphery of said body on said outwardly-directed face for directing at least one beam of light perpendicular to and outwardly from said face towards said facial feature along the path of the X-ray generated by the generating unit to produce at least one light spot on said facial feature to serve as an orientation means for said X-ray unit.
Claim 9
Dependent Claim
23 words
The apparatus of claim 6, wherein said illumination means are two in number and are diametrically opposed to each other about said periphery.
Claim 10
Dependent Claim
12 words
The apparatus of claim 7, wherein said illumination means comprise electric bulbs.
