Matrix-free photoacoustic image reconstruction via sensor-token networks

Photoacoustic tomography (PAT) couples optical absorption contrast with ultrasound resolution, but reconstructing the initial pressure distribution from sparse-view measurements is an ill-posed inverse problem. Iterative compressive-sensing solvers and unrolled deep networks both retain a dependence on the system m...

Matrix-Free Photoacoustic Image Reconstruction via Sensor-Token Self-Attention

The Sensor Attention Network is proposed, a Transformer-based architecture that treats the full time series of each sensor as a token and maps raw measurements directly to the reconstructed image without invoking the system matrix at inference, supporting real-time PAT reconstruction.
