Abstract
Abstract A cephalometric device useful in the preparation of substantially duplicatable skull X-rays is comprised of an elongated boom member having an inner and outer end, a cone holding member connected to the inner end of the boom member, a film cassette holder connected to the outer end of the boom member, a head locator system and an orbital pointer positioned on the boom immediately adjacent to the film cassette holder, and a stand member adapted to position the boom member in a substantially horizontal position. The cephalometric device is adapted to be employed in conjunction with a standard X-ray machine. The combination of cephalometric device and X-ray machine is used to produce lateral view X-ray plates or pictures of the head that are duplicatable within reasonable accuracy.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A portable cephalometric device comprising: a. an elongated boom member having an inner end and an outer end; b. a cone holding member fixed to the inner end of said boom member, said cone holding member adapted to engage the outer periphery of the cone of the head of an X-ray machine to position the longitudinal axis of the cone substantially parallel to the longitudinal axis of the said boom member; c. a holded fixed to the outer end of said boom member, said holder adapted to position the lateral surface of an X-ray film cassette substantially perpendicular to the longitudinal axis of the boom member; d. a head locater system positioned on said boom member between said cone holding member and said holder in close proximity to said holder and comprising (i) spaced bar members, each bar member having an opposed ear locater pin and (ii) a nose positioning member located between said bar members; and e. a stand member adapted to position said boom member in a substantially horizontal position.
Claim 2
Dependent Claim
172 words
A portable cephalometric device comprising: a. an elongated boom member having an inner end and an outer end; b. a cone holding member fixed to the inner end of said boom member, said cone holding member adapted to engage the outer periphery of the cone of the head of an X-ray machine to position the longitudinal axis of the cone substantially parallel to the longitudinal axis of the said boom member; c. a holded fixed to the outer end of said boom member, said holder adapted to position the lateral surface of an X-ray film cassette substantially perpendicular to the longitudinal axis of the boom member; d. a head locater system positioned on said boom member between said cone holding member and said holder in close proximity to said holder and comprising (i) spaced bar members, each bar member having an opposed ear locater pin and (ii) a nose positioning member located between said bar members; and e. a stand member adapted to position said boom member in a substantially horizontal position.
