Abstract

Remote photoacoustic tomography by speckle-analysis which is based on the measurement of the surface tilt is interesting for a lot of medical applications such as endoscopy or wound imaging. In this work, a new model which is capable to simulate the resulting surface tilt after photoacoustic excitation is presented. A Monte Carlo simulation is coupled to a stress simulation which allows the determination of the temporal surface deformation and the resulting tilt. A first comparison to experimental results from literature is done and discussed. In future, this model might help to optimize the speckle-sensing technique for photoacoustic signal detection. Furthermore, it could be used to develop and test image reconstruction algorithms.
