Abstract

Digital fluoroscopic image acquisition, processing and storage for ventriculography, coronary artery and bypass graft imaging involves many practical considerations. Issues of sufficiency in terms of spatial, temporal, gray scale resolution and intravascular contrast sensitivity arise when 35mm cineradiographic film acquisition is replaced by digital fluoroscopy as the primary imaging modality. We have qualitatively and quantitatively evaluated and compared digital fluoroscopic and cineradiographic systems for cardiovascular image acquisition, storage and display in the cardiac catheterization laboratory. A digital fluoroscopic system (Siemens Digitron I) was evaluated and compared favorably to 35mm cineradiography in temporal resolution. Spatial resolution of the digital system was poorer, but contrast sensitivity (with digital subtraction) far exceeded the capabilities of cineradiography. As further modifications are made to adapt digital systems to the cardiac catheterization laboratory, complete replacement of 35mm cineradiography by digital vascular imaging systems is likely in the near future.
