Title:  Acoustic Source and Sound Speed Imaging with Application to Photoacoustic Tomography: A Numerical Study

Abstract: We present numerical algorithms to image passive acoustic sources (resp., sound speed) in the absence of sound speed (resp., source) information. The measurement is the boundary wave field and its spatial derivatives. The algorithms are validated with numerical examples. An application scenario is Photoacoustic Tomography, a multi-wave imaging modality where acoustic sources in unknown biological tissue are to be imaged.

The presentation is based on joint work with G. Huang, J. Qian, S. Qin, R. Wang.
