FIGURE 3. Plots of QGS LVEF (A) and LVEF by our method (B) vs. targeted LVEF (tLVEF) and targeted end-diastolic volume (EDV). For phantoms with large EDVs (EDV 80 mL), QGS LVEF and LVEF by our method closely approximate tLVEF. However, for small hearts (EDV < 80 mL), our method produced better results than did QGS method.
