A jointed feature fusion framework for photoacoustic image reconstruction

open access: yesPhotoacoustics, 2023
The standard reconstruction of Photoacoustic (PA) computed tomography (PACT) image could cause the artifacts due to interferences or ill-posed setup. Recently, deep learning has been used to reconstruct the PA image with ill-posed conditions.
