Score-based Diffusion Models for Photoacoustic Tomography Image Reconstruction

ICASSP 2024accepted

Photoacoustic tomography (PAT) is a rapidly-evolving medical imaging modality that combines optical absorption contrast with ultrasound imaging depth. One challenge in PAT is image reconstruction with inadequate acoustic signals due to limited sensor coverage or due to the density of the transducer…
