Abstract
A6struct-The distribution of heat generation by viscous loss in infinitely long cylinders and spheres is estimated, based on the lossless acoustic wave distributions resulting from an incident plane wave. The characteristics of the objects are typical of tissue, while the lossless surrounding medium is similar to water. Impedance mismatches of up to 20 percent are considered for 1 < ka < 40. Plots of typical heat generation distributions are presented, and apparent trends are summarized. The greatest spatial nonunifonnity and highest peaks of heat generation were found for maximum ka and impedance mismatch.
