Paper Abstract

Quantitation of the severity of coronary obstructions from automatically detected con-tours is limited to the assessment of the obstruction diameter and percent diameter stenosis in that particular view. Even if an obstruction is analyzed trom two views, the computed cross-sectional area does not provide a reliable measure for asymmetric lesions. A densitometric technique is described which attempts to provide measures about cross-sectional areas from a single view on the basis of the measured brightness levels within the arterial segment. Phantom studies show that the accuracy of the assessment of percent area stenosis of obstructions equals 2.79% (s.d. 1.76%) with a computed densitometric transfer function.
