Stochastic EM methods with Variance Reduction for Penalised PET Reconstructions
Zeljko Kereta, Robert Twyman, Simon Arridge +2
Expectation-maximization (EM) is a popular and well-established method for image reconstruction in positron emission tomography (PET) but it often suffers from slow convergence. Or…
Penalized PET/CT Reconstruction Algorithms with Automatic Realignment for Anatomical Priors
Yu-Jung Tsai, Alexandre Bousse, Simon Arridge +3
Two algorithms for solving misalignment issues in penalized PET/CT reconstruction using anatomical priors are proposed. Both approaches are based on a recently published joint moti…
Quantitative photoacoustic tomography using forward and adjoint Monte Carlo models of radiance
Roman Hochuli, Samuel Powell, Simon Arridge +1
Forward and adjoint Monte Carlo (MC) models of radiance are proposed for use in model-based quantitative photoacoustic tomography. A 2D radiance MC model using a harmonic angular b…
Reconstruction-classification method for quantitative photoacoustic tomography
Emma Malone, Samuel Powell, Ben T. Cox +1
We propose a combined reconstruction-classification method for simultaneously recovering absorption and scattering in turbid media from images of absorbed optical energy. This meth…
Gradient-based quantitative image reconstruction in ultrasound-modulated optical tomography: first harmonic measurement type in a linearised diffusion formulation
Samuel Powell, Simon R. Arridge, Terence S. Leung
Ultrasound-modulated optical tomography is an emerging biomedical imaging modality which uses the spatially localised acoustically-driven modulation of coherent light as a probe of…
