Dear Sir,
I am working on breast cancer detection through simulation of photoacoustic imaging.
Before k-wave simulation, I have done the simulation of light propagation inside the breast tissue model through 3d Monte-Carlo simulation. 3d absorption profile obtained from this simulation was used as a source in the k-wave simulation. Acoustic wave propagation through the medium and its detection using planar array were achieved with k-wave. But I wanted to know whether it is correct to place the absorption profile as a source in the k-wave simulation?
I am also eager to find any mechanism or provision to generate acoustic wave from the absorption profile in the k-wave toolbox so that this generated acoustic wave will become a source in the k-wave simulation.

Hi Prabhakar,
If your laser pulse is short enough to assume that stress confinement holds, you can directly assign the absorbed energy distribution from your Monte-Carlo simulation to
source.p0. Note, you will need to multiply by the Gruneisen parameter if you care about absolute values of pressure (e.g., see here).Brad
