A Hybrid Reconstruction Approach for Absorption Coefficient by Fluorescence Photoacoustic Tomography
Chao Wang, Tie Zhou
In this paper, we propose a hybrid method to reconstruct the absorption coefficient by fluorescence photoacoustic tomography (FPAT), which combines a squeeze iterative method (SIM)…
On Iterative Algorithms for Quantitative Photoacoustic Tomography in the Radiative Transport Regime
Chao Wang, Tie Zhou
In this paper, we describe the numerical reconstruction method for quantitative photoacoustic tomography (QPAT) based on the radiative transfer equation (RTE), which models light p…
Superiorized iteration based on proximal point method and its application to XCT image reconstruction
Shousheng Luo, Yanchun Zhang, Tie Zhou +1
In this paper, we investigate how to determine a better perturbation for superiorized iteration. We propose to seek the perturbation by proximal point method. In our method, the di…
On Relaxed Averaged Alternating Reflections (RAAR) Algorithm for Phase Retrieval from Structured Illuminations
Ji Li, Tie Zhou
In this paper, as opposed to the random phase masks, the structured illuminations with a pixel-dependent deterministic phase shift are considered to derandomize the model setup. Th…
Numerical Optimization Algorithm of Wavefront Phase Retrieval from Multiple Measurements
Ji Li, Tie Zhou
Wavefront phase retrieval from a set of intensity measurements can be formulated as an optimization problem. Two nonconvex objective models (MLP and its variants LS) based on maxim…
On Gradient Descent Algorithm for Generalized Phase Retrieval Problem
Ji Li, Tie Zhou
In this paper, we study the generalized phase retrieval problem: to recover a signal from the measurements $y_r=\lvert \langle\bm{a}_r,\bm{x}\rangle\rvert^2…
Moment-based cosh-Hilbert Inversion and Its Applications in Single-photon Emission Computed Tomography
Shousheng Luo, Jiansheng Yang, Tie Zhou
The inversion of cosh-Hilbert transform (CHT) is one of the most crucial steps for single-photon emission computed tomography with uniform attenuation from truncated projection dat…
Superiorization of EM Algorithm and Its Application in Single-Photon Emission Computed Tomography(SPECT)
Shousheng Luo, Tie Zhou
In this paper, we presented an efficient algorithm to implement the regularization reconstruction of SPECT. Image reconstruction with priori assumptions is usually modeled as a con…
