Typical computational time (in seconds) for reconstructing the initial pressure distribution for the various methods presented in this work. Note that the time taken for building the system matrix (375 seconds) was excluded from this.
| Method | K-Wave time-reversal | LSQR (λ = 0.01) | Optimal LSQR | BPD with LSQR (λ = 0.01) | BPD with Optimal LSQR |
|---|---|---|---|---|---|
| Time (seconds) | 111.8 | 53.0 | 321.8 | 53.3 | 322.8 |
