- FIGURE 1.
Development and description of phantom. (A) Ventricles were cut off at atrioventricular border. (B) Single-walled RV was attached to double-walled LV. (C) Horizontal long-axis slice (top left), short-axis slice (top right), and vertical long-axis slice (bottom) of activity distribution in phantom. (D) Detail of biventricular model. Valves 1 are used to fill septal wall with gel; valves 2 are used to deaerate tubings, to inject tracer, and to empty ventricles for volume measurements. Valves 3 are in- and outgoing tubes to ventricles. (E) Overview of experimental model, with piston pump in back, membranes in middle, and ventricular model at front.

Linear regression and Bland-Altman analysis of mean calculated left and right ventricular volumes (MLVV and MRVV) vs. real left and right ventricular volumes (RLVV and RRVV).
- FIGURE 3.
Linear regression and Bland-Altman analysis of mean calculated LVEF and RVEF (MLVEF and MRVEF) vs. real LVEF and RVEF (RLVEF and RRVEF).
- FIGURE 4.
Interobserver variability shown by linear regression of LVEF and RVEF and volume measurements of 2 different observers.
- FIGURE 5.
Intraobserver variability shown by linear regression of LVEF and RVEF and volume measurements of 2 observations for same observer.
