Fig. 2. Overview of the placenta phantom.

(A) Assembled model just before the MRI measurement. (B) Exploded view of the model, showing from the top to bottom the inlet module, the lid with venous ports, and the cotyledon structure attached to a supporting structure. For better visualization of the position of arterial inlets (red) and venous outlets (blue), just the cotyledon replica is shown rotated by 180°. The four variations of the arterial ports as shown in (D) to (G) can be slotted in at position (C).
