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.
