Paper Abstract

A high resolution hybrid system for video densitometry is introduced. The system utilizes 100 mm spot films taken directly from the output phosphor of an image intensifier. These images are magnified using a zoom lens and subsequently digitized by means of a Plumbicon TV camera and a Quantex DS-30 video image processor. The zoomed images are digitized in a 512x512 format with 8 bits/pixel. These images are then transferred into a Data General NOVA 3 computer for video densitometric analysis. The limiting resolution of the system is the resolution at the output phosphor of the image intensifier. Experimental results using phantoms to evaluate the hybrid system's ability to quantitate percentage stenosis are presented.
