Dual-Domain Self-Supervised Artifact Removal Framework for Photoacoustic Computed Tomography
Yucheng Zhou, Shuang Li, Yu Zhang, Yibing Wang, Chulhong Kim, Seongwook Choi, et al.
Photoacoustic Computed Tomography (PACT) often faces severe challenges from reconstruction artifacts due to sparse detection conditions. In this work, based on the distinct differences in artifact patterns between back-projection-based and Fourier-based reconstruction algorithms,…
