Fig. 1

Exploded view (top) of phantom design and tailored cross section (bottom) to illustrate inner phantom connections. The arrows indicate flow direction and magnitude, and its color differentiates between arterial input (red) and venous output (blue). The middle phantom part comprises of the simulated left ventricular cavity and three surrounding myocardial segments. The two outer parts contain the in- and outlet connections to the flow circuit and the internal branches to the segments. These branches correspond to the main coronary arteries, i.e., the left anterior descending coronary artery (LAD), right coronary artery (RCA) and left circumflex coronary artery (LCX). The phantom parts are fastened together with nylon screws whereby silicone seals are placed in between the parts for waterproofing
