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.
