Fig. 2 — Fluid circuit diagram of measurement set-up. The phantom simulates first-pass left ventricular flow and myocardial perfusion. The cardiac phantom is inserted into a thorax phantom, comprising the scanner’s field of view. The myocardium (MYO) consists of three segments surrounding the left ventricular cavity (LVC). The individual components include: 1) water reservoirs, 2) one-way check valves, 3) an immersion pump, 4) a clinical contrast media injector, 5) an ultrasonic flow sensor, 6) turbine flow sensors, 7) a pressure sensor, and 8) adjustable resistances. The components between A and B concern one myocardial segment circuit. In total there are three such circuits connected in parallel. Water flows from top left to bottom left and right.
