Cavitation is involved in a number of therapeutic applications of ultrasound (US) [1] [2] [3]. Monitoring these treatments requires real-time imaging of the cavitation activity during treatment. For this reason, Passive Acoustic Mapping (PAM) of cavi

Most cardiomyocytes in the left ventricle wall are grouped in aggregates of four to five units that are quasi-parallel to each other. When one or more “cardiomyocyte aggregates” are delimited by two cleavage planes, this defines a “sheetlet”
