Abstract

A digital fluorographic system for displaying images comprising video and multi format display means which are each provided image data from large size matrices (1024×1024). The data is compressed and is provided to the video display at speeds that preclude the necessity of using broad bandwidth equipment.

Claims

1. A digital fluorographic system for displaying fluorographic images, said system comprising:

image acquisition means for acquiring digital images for the interior of a subject'"'"'s body, means for providing video displays of the acquired images, means for providing photographic displays of said acquired images, an image matrix being of a first size for holding digital data, first transfer means for supplying the image data to said video display means as data from a smaller size matrix than said first size matrix, wherein said smaller size matrix is derived from first size matrix, and second transfer means for supplying the data from said first size matrix to said means for providing photographic displays of the first size matrix.

2. The system of claim 1 wherein said first size matrix comprises 1024×

1024 elements and said smaller size matrix comprises 512×

512 elements.

3. The system of claim 1 wherein said second transferring means comprises slow scanning means.

4. The system of claim 3 wherein said first transfer means comprises compression means such that the data can be transferred without necessitating the use of broad bandwidth equipment.

5. The system of claim 3 wherein said first transfer means comprises portion selector read out means such that the data can be transferred without necessitating the use of broad bandwidth equipment.

6. The system of claim 1 wherein said second transfer means is separate from said first transfer means.

7. The system of claim 6 wherein said first transfer means includes means fast enough to read-out portion of said first sized matrix so that said video display comprises equipment of average bandwidth.

8. The system of claim 7 wherein said first transfer means comprises data compression means.

9. The system of claim 7 wherein said first transfer means comprises portion selector read-out means.

10. The system of claim 8 wherein said first size matrix comrises 1024×

1024 elements and said smaller size matrix compises 512×

512 elements.
