Improved fluoroscopic and cine-radiographic display with pulsed exposures and progressive TV scanning

In fluoroscopic image display, moving objects lose resolution because of continuous x-ray exposure and interlaced TV scanning. Significant improvements can be obtained with progressive TV scanning synchronized to short x-ray pulses occurring at a rate of 30 Hz. Modification of the x-ray generator and addition of a progressive-scan TV camera coupled with a scan converter (progressive to interlaced) allows one to maintain fluoroscopy radiation levels, prevent image refresh flicker, and use existing low bandwidth interlaced monitors for optimum image quality.
