Abstract

Color distributions of absorption of acoustic energy in spheres due to an incident plane wave are presented. The characteristics of the spheres are typical of tissue, while the lossless surrounding medium is similar to water. Effects of varying parameters such as sound velocity, density, and object size on the solution to the wave equation are discussed and demonstrated in the images. Larger objects and those with lower acoustic impedance than the surrounding medium have areas of focused and relatively more intense heating. For short duration exposure the images represent the spatial distributions of relative rates of temperature rise.
