Optoacoustic acoustic transients arising from optical absorption and thermoelastic expansion contain information on the optical properties of the irradiated medium. The profile of the optoacoustic signal generated by the absorber, for example from cancer cells, has a complex geometric structure, can be represented by the convolution of acoustic waves emitted by a number of small spherical sources.
