Abstract
Abstract A fluoroscopic image is processed digitally using a television camera operating at a frame rate of at least 30 frames per second viewing the image and providing an analog video output, a digitizer which digitizes the analog video output to provide digital information representative of the analog signal, a plurality of frame processors which carry out arithmetic and logical operations on the digital image information and are operable at the frame rate of the television camera coupled to the output of the digitizer, a 2-D filter operable at the frame rate of the television camera coupled to said frame processors, a converter and interface to convert digital image information processed in the frame processors and 2-D filter back into an analog signal and television display coupled to the output of the converter for displaying the processed signal.

Claim 1
Independent Claim
196 words
Apparatus for processing a fluoroscopic image comprising: a. a television camera operating at a frame rate of at least 30 frames per second providing an analog video output; b. means to digitize said analog video output to provide digital information representative of the analog signal; c. means for processing said digital image including a plurality of frame processors coupled in series for carrying out arithmetical and logical operations on said digital image information and operable at the frame rate of said television camera coupled to receive the output of said digitizer; d. means to convert digital image information processed in said means for processing back into an analog signal; e. a wide-band tape recorder, having an input and an output; f. means for coupling said digital image information, before processing, to the input of said wide-band tape recorder at the same time that processed information is being provided to a television display; g. means for coupling the output from said wide-band tape recorder to said means for processing, such that unprocessed digitized information will be recorded on said wide-band tape recorder and may later be played back through said system and processed therein in non-real time.
