Claim 1
Independent Claim
168 words
An apparatus for monitoring alignment of an X-ray beam, comprising: a housing means for providing electrical signals responsive to X-ray beam intensities during alignment of the X-ray beam, comprising a protective filter layer transparent to X-rays but opaque to visible light, a layer of X-ray fluorescent material, adjacent to said filter layer, and a photoresistor in close proximity to said X-ray fluorescent material, for providing variable resistance responsive to said X-ray beam intensities, audio frequency generating means, electrically connected to said photoresistor, for generating variable frequencies corresponding to said variable resistance, sound generating means, electrically connected to said audio frequency generating means, for generating sounds corresponding to said variable frequencies, and low voltage power supply means connected to said monitoring apparatus by a switching means, for enabling said apparatus, whereby, by monitoring the frequency of the sounds emitted by said sound generating means, an X-ray beam is aligned to a desired alignment by adjusting the X-ray beam to produce a sound corresponding to a desired X-ray beam intensity.
Claim 2
Independent Claim
168 words
An apparatus for monitoring alignment of an X-ray beam, comprising: a housing means for providing electrical signals responsive to X-ray beam intensities during alignment of the X-ray beam, comprising a protective filter layer transparent to X-rays but opaque to visible light, a layer of X-ray fluorescent material, adjacent to said filter layer, and a photoresistor in close proximity to said X-ray fluorescent material, for providing variable resistance responsive to said X-ray beam intensities, audio frequency generating means, electrically connected to said photoresistor, for generating variable frequencies corresponding to said variable resistance, sound generating means, electrically connected to said audio frequency generating means, for generating sounds corresponding to said variable frequencies, and low voltage power supply means connected to said monitoring apparatus by a switching means, for enabling said apparatus, whereby, by monitoring the frequency of the sounds emitted by said sound generating means, an X-ray beam is aligned to a desired alignment by adjusting the X-ray beam to produce a sound corresponding to a desired X-ray beam intensity.
Claim 3
Dependent Claim
25 words
