Numerical prediction and measurement of optoacoustic signals generated in PVA-H tissue phantoms
Abstract
Abstract: We present numerical simulations of optoacoustic (OA) signals, complementing laboratory experiments on melanin doped polyvinyl alcohol hydrogel (PVA-H) tissue phantoms. We review the computational approach to model the underlying mechanisms, i.e. optical absorption of laser energy and acoustic propagation of mechanical stress, geared toward experiments that involve absorbing media with homogeneous acoustic properties. We apply the numerical procedure to predict signals observed in the acoustic near- and farfield in both, forward and backward detection mode, in PVA-H tissue phantoms (i.e. an elastic solid). Further, we report on verification tests of our research code based on OA experiments on dye solution (i.e. a liquid) detailed in the literature and benchmark our 3D procedure via limiting cases described in terms of effectively 1D theoretical approaches.
