Processing time for reconstruction of a single frame of cavitation map with the number of pixels of $N_x\times \hspace{0.17em}{N}_z$ and the integration time $T$. $N_t$ is the number of time samples to be integrated. The number of channels (i.e., receiving elements, $N_{\mathbf{E}}$) was 64. The average processing time was measured from 20 repeated tests and the error bars denote two standard deviations.
