Color map generation techniques for simultaneously displaying different types of cavitation activity on a digital image

Abstract

A method of simultaneously outputting a plurality of cavitation types on a digital image is provided. The method includes detecting acoustic emissions corresponding to the plurality of cavitation types, the plurality of cavitation types including at least some combination of linear scatter, stable cavitation, and inertial cavitation, generating, based on the acoustic emissions, a two-dimensional color map of the plurality of cavitation types on the digital image, the two-dimensional color map includes a first acoustic emission corresponding to linear scatter or stable cavitation and a second acoustic emission corresponding to linear scatter or inertial cavitation, and outputting on the digital image, displayed on the display of the computing device, the two-dimensional color map of the plurality of cavitation types.
