Systematic validation of time-resolved diffuse optical simulators via non-contact SPAD-based measurements
Weijia Zhao, Linlin Li, Kaiqi Kuang +6
Objective: Time-domain diffuse optical imaging (DOI) requires accurate forward models for photon propagation in scattering media. However, existing simulators lack comprehensive ex…
NeuFMT: Optical-Property-Adaptive Fluorescence Molecular Tomography via Implicit Neural Representation
Shihan Zhao, Jianru Zhang, Yanan Wu +6
Fluorescence Molecular Tomography (FMT) is a promising technique for non-invasive 3D visualization of fluorescent probes, but its reconstruction remains challenging due to the inhe…
A Warm-basis Method for Bridging Learning and Iteration: a Case Study in Fluorescence Molecular Tomography
Ruchi Guo, Jiahua Jiang, Bangti Jin +2
Fluorescence Molecular Tomography (FMT) is a widely used non-invasive optical imaging technology in biomedical research. It usually faces significant accuracy challenges in depth r…
Augmented Flexible Krylov Subspace methods with applications to Bayesian inverse problems
Malena Sabate Landman, Jiahua Jiang, Jianru Zhang +1
This paper presents two new augmented flexible (AF)-Krylov subspace methods, AF-GMRES and AF-LSQR, to compute solutions of large-scale linear discrete ill-posed problems that can b…
