Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
100 words
A medical diagnostic video imaging system for providing display images of objects, said system comprising: (a) video processing means for processing data receiving from video camera means to convert said data to digital data; (b) computer means for operating on the digital data to enhance the images of the objects; (c) display means for displaying the enhanced images; (d) means for selectively providing video data to said processor from either a radiographic or fluorographic source, and (e) said radiographic source including film illuminator means whereby an x-ray film recorded in the past can be readily compared with a fluorographic display.
Claim 2
Dependent Claim
100 words
A medical diagnostic video imaging system for providing display images of objects, said system comprising: (a) video processing means for processing data receiving from video camera means to convert said data to digital data; (b) computer means for operating on the digital data to enhance the images of the objects; (c) display means for displaying the enhanced images; (d) means for selectively providing video data to said processor from either a radiographic or fluorographic source, and (e) said radiographic source including film illuminator means whereby an x-ray film recorded in the past can be readily compared with a fluorographic display.
Claim 3
Dependent Claim
28 words
The imaging system of claim 1 wherein said video processing means comprises a radiographic channel and a fluorographic channel, each of said channels having a separate video camera.
Claim 4
Dependent Claim
35 words
The imaging system of claim 2 wherein said means for selectively providing video data comprises means for selecting the output of either the camera in said radiographic channel or the camera in said fluorographic channel.
Claim 5
Dependent Claim
13 words
The imaging system of claim 3 wherein said selecting means comprises gate means.
Claim 6
Dependent Claim
32 words
The imaging system of claim 3 wherein said selecting means comprises switch means, said switch means operates to connect the output of one channel while disconnecting the output of the other channel.
Claim 7
Dependent Claim
31 words
The system of claim 1 wherein said video processing means comprises a radiographic channel and a fluorographic channel, each of said channels using a same video camera to provide said data.
Claim 8
Dependent Claim
34 words
The system of claim 6 wherein said means for selectively providing data comprises selecting means for causing said same video camera to receive inputs from either said radiographic channel or from said fluorographic channel.
Claim 9
Dependent Claim
13 words
The system of claim 7 wherein said selecting means comprises optical gate means.
Claim 10
Dependent Claim
39 words
The system of claim 7 wherein said selecting means comprises multiplexing means to enable said radiographic channel and said fluorographic channel to be used substantially simultaneously, whereby the comparison of the x-ray film and the fluorographic display is facilitated.
Claim 11
Dependent Claim
38 words
The system of claim 2 wherein said display means comprises multiformat means for providing a film record of the image of the fluorographic channel, and means for using said film record in said radiographic channel for further enhancement.
Claim 12
Dependent Claim
24 words
The system of claim 1 wherein said display means comprises multi-format means to provide side-by-side display of the x-ray film and the fluorographic display.
