This article offers a perspective on photoacoustic tomography (PAT) under realistic
scenarios. While PAT has gained much attention in preclinical and clinical research, most
early works used image reconstruction techniques based on ideal assumptions, and thus
these techniques may not be fully effective in real environments. In this work, we consider
such non-ideal conditions as a limited view, limited bandwidth, lossy medium, or
heterogeneous medium. More importantly, we use k-Wave simulation to numerically …
