Paper Abstract

Using standard angiographic equipment involving an image intensifier-video camera combination, subpixel precision can be achieved in the estimation of blood vessel diameter using 512x512x8 digital image resolution. Analyses were carried out with blood vessel phantoms ranging from 1.27 to 5.46 mm in diameter. The relationship between actual and measured diameters was found linear between 3 and 5.46 mm; below 3mm it became non-linear. The studies were performed under ideal conditions with a water block as scattering medium, without motion and without subtraction on uniform background.
