Researchers have developed a new Transformer-based architecture called the Sensor Attention Network (SAN) for photoacoustic tomography (PAT). This network treats sensor time series data as tokens, enabling direct mapping from raw measurements to reconstructed images without relying on the system matrix during inference. SAN significantly reduces reconstruction time, making real-time PAT feasible, and demonstrates superior performance over existing methods like ISTA, split-Bregman total variation, and learned ISTA in terms of SSIM, PSNR, and NMSE.
