Figure Lengend Snippet: Cavitation mapping entailed the ( a ) creation of a spectral map by transforming the raw signal of a signal channel through Matlab’s built-in STFT function, ( b ) the fabrication of a baseline and comparison to a frame of interest by extracting data based on selected user-defined frequencies, and ( c ) a comparison of baseline and a selected acquisition for mapping potential regions of stable and inertial cavitation onto a reconstructed plane wave frame.
Article Snippet: Cavitation mapping involved transforming the raw time-domain signal of an individual channel into Matlab’s built-in short-time Fourier transform (STFT) function ( a) with inputs shown in mapped with an amplitude logarithmic scale.
