Diagram of experimental setup.
Time sequence of data acquisition and HIFU waves.
Results from five separated experiments with an intensity of 1000 W/cm2, 14 s duration. (a) and (b) the averaged PA amplitude and temperature with standard error of the mean (SEM), respectively, (c) the relation between the PA amplitude and the calculated thermal dose from the averaged temperature, and (d) photographs of beef kidney after HIFU treatment.
PA amplitude as the function of temperature and the linear fit. The coefficient of determination R2 = 0.8727.
(a) PA amplitudes from a beef kidney sample placed in a 50 °C temperature water bath; (b) the relation between the PA amplitude and the calculated thermal dose.
