Paper Abstract

A method to construct anthropomorphic vascular flow phantoms which incorporate disease states (e.g., stenosis) has been developed. The new technique is an adaptation of an existing technique that fabricates disease free vascular phantoms. Using the modified process, three carotid artery bifurcation phantoms have been built. One phantom was free of stenotic disease, and the other two phantoms have geometries corresponding to (1) a 70% concentric stenosis, and (2) a 70% eccentric stenosis in the internal carotid artery. Collectively, these three phantoms allow for comparative research between and in vitro evaluation of a number of medical imaging instruments, including (1) x-ray based systems (e.g., digital subtraction angiography and computed tomography), (2) Magnetic Resonance Imaging (MRI) scanners, and (3) Doppler Ultrasound (US) instruments. Here, representative images from x-ray and MR imaging instruments are shown. Pulsed Doppler US velocity spectra collected within the lumen of the phantoms are also presented.
