PAGS: Autofocusing Photoacoustic Tomography via Speed-of-Sound-Adaptive Gaussian Splatting
PAGS, a differentiable framework for blind autofocusing PACT via speed-of-sound-adaptive Gaussian splatting, is proposed, which demonstrates improved reconstruction sharpness under heterogeneous acoustic media, robustness to sparse-view sampling, and computational benefits from the analytic Gaussian projection.
