Figure 1 Region-of-interest placement (solid white lines) for in vitro and human studies. (A) Contrast image of the perfusion phantom, left and right echo-dense structure represents the cross-section of the hemodialysis filter and the left-ventricular analogue, respectively. The trapezoidal appearance of the filter is caused by total reflectance on the filter housing. (B) Four-chamber view of a healthy volunteer.
