Resolution Enhancement of Under-sampled Photoacoustic Microscopy Images using Implicit Neural Representations
Youshen Xiao, Sheng Liao, Xuanyang Tian +7
Acoustic-Resolution Photoacoustic Microscopy (AR-PAM) is promising for subcutaneous vascular imaging, but its spatial resolution is constrained by the Point Spread Function (PSF).…
Implicit Neural Representation for Sparse-view Photoacoustic Computed Tomography
Bowei Yao, Shilong Cui, Haizhao Dai +6
High-quality imaging in photoacoustic computed tomography (PACT) usually requires a high-channel count system for dense spatial sampling around the object to avoid aliasing-related…
Limited-View Photoacoustic Imaging Reconstruction Via High-quality Self-supervised Neural Representation
Youshen xiao, Yuting Shen, Bowei Yao +3
In practical applications within the human body, it is often challenging to fully encompass the target tissue or organ, necessitating the use of limited-view arrays, which can lead…
Sparse-view Signal-domain Photoacoustic Tomography Reconstruction Method Based on Neural Representation
Bowei Yao, Yi Zeng, Haizhao Dai +6
Photoacoustic tomography is a hybrid biomedical technology, which combines the advantages of acoustic and optical imaging. However, for the conventional image reconstruction method…
