Table 1.

Cleaning parameters for each transducer. The input electric energy is higher with the standard protocol due to the shape and length differences between signals.

Cleaning parameters
Center frequency 20 kHz
PRF 2 Hz
Cleaning time 60 s
Number of cycles 20
Input electric energy / burst (standard protocol) 250 mJ
Input electric energy / burst (TR protocol) 2 mJ
