Results for Mean and RMS Error in LVV Over the Physiologic Volume Range, and EF and % Error in EF Using the Composite Midpoint Integration Method (Eqn. 1) for LVV Estimation Based on 12, 6, and 4 Slices, Compared With the Pump‐Based Ground Truth EF of 0.403
| Composite Midpoint Method | 12 Slices | 6 Slices Var. 1 | 6 Slices Var. 2 | 6 Slices Mean | 4 Slices Var. 1 | 4 Slices Var. 2 | 4 Slices Var. 3 | 4 Slices Mean |
|---|---|---|---|---|---|---|---|---|
| Mean LVV error, mL | 1.1 | 2.4 | −0.3 | 1.0 | 1.0 | 6.0 | −3.8 | 1.1 |
| Mean error, % | 2.2 | 5.1 | −0.6 | 3.6 | 2.1 | 12.6 | −8.0 | 2.2 |
| RMS error, % | 2.4 | 5.3 | 1.3 | 3.3 | 3.4 | 12.7 | 8.1 | 8.1 |
| EF | 0.412 | 0.414 | 0.409 | 0.412 | 0.431 | 0.392 | 0.413 | 0.412 |
| EF error, % | 2.2 | 2.8 | 1.6 | 2.2 | 7.0 | −2.7 | 2.6 | 2.3 |
EF indicates ejection fraction; LVV, left ventricular cavity volume; RMS, root mean square.
