A Dynamic Arterial Tree Phantom for studies of bolus chasing CT Angiography

Abstract

Computed Tomography (CT) and Magnetic Resonance (MR) imaging techniques have become an important role in diagnosing the vascular diseases. Before a clinical trial of the newly developed techniques, it is essential to evaluate them on a phantom. However, there is no existing arterial tree phantom that serves for flood flows. To that end, we design and develop a Dynamic Arterial Tree Phantom (DATP), which is able to produce many kinds of blood flow pattern through using a programmable pump functions as a heart. Contrast enhanced CT scan is also performed on this phantom for adaptive bolus chasing techniques.
