Abstract
Abstract An improved intraoral fluoroscope adapted for use with an electronic video display system is provided by the present invention. The preferred fluoroscope system comprises (a) a light transparent, phosphor-coated screen, (b) a visible light image conversion system for converting a visible light image to an electrical video signal output comprising one or more, and preferably a plurality, of charge coupled image sensors, the visible light image conversion system being in light communication with the light transparent, phosphor-coated screen, and (c) timing, control and transmission circuitry electrically connecting the light image conversion system to the video display system and adapted to receive and transmit the video signal output from the visible light image conversion system to the video display system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
An intraoral fluoroscope adapted for use with an electronic video display system comprising: (a) sensing means for converting an invisible radiant energy image to a visible light image; (b) a light image conversion system for converting a visible light image to an electrical video signal output comprising at least one charge coupled image sensor, said image conversion system being in visible light communication with said sensing means and said light image conversion system and sensing means adapted for insertion into the human mouth; and (c) timing, control and transmission means electrically connecting said conversion system and said video display system and adapted to receive and transmit said video signal output from said conversion system to said video display system.
Claim 2
Dependent Claim
119 words
An intraoral fluoroscope adapted for use with an electronic video display system comprising: (a) sensing means for converting an invisible radiant energy image to a visible light image; (b) a light image conversion system for converting a visible light image to an electrical video signal output comprising at least one charge coupled image sensor, said image conversion system being in visible light communication with said sensing means and said light image conversion system and sensing means adapted for insertion into the human mouth; and (c) timing, control and transmission means electrically connecting said conversion system and said video display system and adapted to receive and transmit said video signal output from said conversion system to said video display system.
Claim 3
Dependent Claim
30 words
The fluoroscope of claim 1 wherein said sensing means comprises a screen member, a phosphor material for converting an invisible radiant energy image to a visible light image deposited thereon.
Claim 4
Dependent Claim
27 words
The fluoroscope of claim 2, wherein said sensing means is in direct visible light communication with and in close physical proximity to said light image conversion system.
Claim 5
Dependent Claim
23 words
The intraoral fluoroscope of claim 1 wherein said visible light image conversion system comprises a plurality of electrically interconnected charge coupled image sensors.
Claim 6
Dependent Claim
117 words
An intraoral fluoroscope adapted for use with an electronic video display system comprising: (a) a non-lens, x-ray transparent screen member; (b) an x-ray image conversion system for converting an x-ray image into an electrical video signal output comprising at least one charge coupled image sensor, the image conversion system being in direct x-ray communication with and in close physical proximity to the said screen member and said x-ray image conversion system and screen member adapted for insertion into the human mouth; and (c) timing, control and transmission means electrically connecting said conversion system and said video display system and adapted to receive and transmit said video signal output from said conversion system to said video display system.
Claim 7
Dependent Claim
117 words
An intraoral fluoroscope adapted for use with an electronic video display system comprising: (a) a non-lens, x-ray transparent screen member; (b) an x-ray image conversion system for converting an x-ray image into an electrical video signal output comprising at least one charge coupled image sensor, the image conversion system being in direct x-ray communication with and in close physical proximity to the said screen member and said x-ray image conversion system and screen member adapted for insertion into the human mouth; and (c) timing, control and transmission means electrically connecting said conversion system and said video display system and adapted to receive and transmit said video signal output from said conversion system to said video display system.
