Abstract

Photoacoustic tomography (PAT) image quality is degraded by transducer-related distortions. This study employed conventional l1-norm based deconvolution and deep learning based deconvolution to compensate spatial impulse response, achieved 40/81 improvement in terms of SSIM/PSNR over backprojection reconstruction. © 2024 The Author(s).
