Self-Supervised Angular Deblurring in Photoacoustic Reconstruction via Noisier2Inverse

ArXi:2604.15681v1 Announce Type: new Photoacoustic tomography (PAT) is an emerging imaging modality that combines the complementary strengths of optical contrast and ultrasonic resolution. A central task is image reconstruction, where measured acoustic signals are used to recover the initial pressure distribution. For ideal point-like or line-like detectors, several efficient and fast reconstruction algorithms exist, including Fourier methods, filtered backprojection, and time reversal.
