New PAGS framework improves photoacoustic tomography with speed-of-sound adaptation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PAGS, a novel framework for photoacoustic computed tomography (PACT) that addresses the challenge of unknown speed-of-sound heterogeneity. This method uses speed-of-sound-adaptive Gaussian splatting to achieve blind autofocusing, representing the initial pressure field with sparse Gaussian photoacoustic sources. PAGS directly updates source parameters and the speed-of-sound field from measured data, eliminating the need for calibrated speed-of-sound priors and demonstrating improved reconstruction sharpness and computational efficiency.

    PAGS: Autofocusing Photoacoustic Tomography via Speed-of-Sound-Adaptive Gaussian Splatting

    arXiv:2608.25472v1 Announce Type: new Abstract: Photoacoustic computed tomography (PACT) combines optical absorption contrast with acoustic detection for high-resolution deep-tissue imaging. A persistent challenge is that unknown speed-of-sound (SoS) heterogeneity changes acousti…
