Sparse Reconstruction for Fluorescence Lifetime Imaging Microscopy with Poisson Noise

Lasith Adhikari

We present a novel, three-stage method to solve the fluorescence lifetime imaging problem under low-photon conditions. In particular, we reconstruct the fluorophore concentration along with its support and fluorescence lifetime from the time-dependent measurements of scattered light exiting the domain. Because detectors used for these problems are photon counting devices, measurements are corrupted by Poisson noise. Consequently, we explicitly consider Poisson noise in conjunction with SPIRAL-$\ell_p$ -- a sparsity-promoting nonconvex optimization method -- to solve this problem.

Super-resolution spectral analysis for ultrasound scatter characterization

Konstantinos Diamantis

Parametric Bayesian spectral estimation methods have been previously utilized to improve frequency resolution. Ultrasound signals have been tested in such methods resulting in higher precision frequency detection compared to common non-parametric spectral estimation methods based on the Fourier transform. Such a technique using a reversible jump Markov Chain Monte Carlo algorithm has been developed to fully characterize signals and in addition to frequency, to provide amplitude and noise estimation.

A fast weighted stochastic gradient descent algorithm for image reconstruction in 3D computed tomography

RababKreidieh Ward

Abstract—We describe and evaluate an algorithm for image reconstruction in 3D x-ray computed tomography. The proposed algorithm is similar to the class of projected gradient methods. The gradient descent for reducing the measurement misfit term is carried out using a stochastic gradient iteration and the gradient directions are weighted using weights suggested by parallel coordinate descent.
