Abstract
Contiguous orthonormal arterial cross sections, segment lengths, and c urvature were semiautomatically quantified from helical computed tomog raphic (CT) angiographic data in phantoms and two patients. Measuremen ts of mean diameter and curvature correlated with reference values (r( 2) = .99), and mean fractional errors were 0.07 and 0.06 for mean diam eter and curvature measurements, respectively. Volumetric measurement showed a potential to increase the accuracy, precision, and diagnostic utility of CT angiography.
