These MATLAB codes were developed while I was working in Dr. Jinyi Qi's Lab at UC Davis Biomedical Engineering.
KER v0.11:
a MATLAB toolbox to demonstrate the kernel method for tomographic image reconstruction.
KER_v0.11: Kernelized expectation maximization (KEM) algorithm for PET image reconstruction. [Download KER_v0.11.zip]
Note: version 0.1 has a bug regarding setting up the path. It is corrected in the new version 0.11.
PLOT v1.0:
a MATLAB toolbox for penalized likelihood (PL) image reconstruction using optimization transfer (OT) algorithms.
PLOT_v1.0: De Pierro's expectation maximization (DEM), preconditioned conjugate gradient (PCG), optimization transfer descent (OTD) and trust optimization transfer (TOT) algorithms for PL reconstruction with pixel-based and patch-based edge-preserving regularizations. [Download PLOT_v1.0.zip]
DIRECT v0.1:
a MATLAB toolbox demonstrating the algorithms developed for dynamic image reconstruction for emission computed tomography (DIRECT).
DIRECT_v0.1: generalized optimization transfer algorithms with the EM surrogate (OT-EM) and with the separable paraboloidal surrogates (OT-SP) for nonlinear parametric image reconstruction from dynamic PET projection data [Download DIRECT_v0.1.zip]
