An overview of the theory of 4D image reconstruction for emission tomography is given along with a review of the current state of the art, covering both positron emission tomography and single photon emission computed tomography (SPECT). By viewing 4D image reconstruction as a matter of either linear or non-linear parameter estimation for a set of spatiotemporal functions chosen to approximately represent the radiotracer distribution, the areas of so-called ‘fully 4D’ image reconstruction and… 
Multi-dataset image reconstruction for longitudinal and multi-tracer positron emission tomography
TLDR
Experimental results demonstrated how changing the characteristics encouraged in difference images can affect the reconstruction of tumour regions in the resulting PET images, highlighting the need for application-specific selection and validation of difference-image priors.
Probabilistic Graphical Models for Dynamic PET: A Novel Approach to Direct Parametric Map Estimation and Image Reconstruction
TLDR
A new probabilistic modeling strategy based on the key assumption that activity time course would be subject to uncertainty even if the parameters of the underlying dynamic process are known is introduced, leading to a hierarchical model that is flexible to an arbitrary choice of kinetic models, and enables the inclusion of arbitrary (sub)differentiable priors for parametric maps.
Probabilistic Graphical Modeling approach to dynamic PET direct parametric map estimation and image reconstruction
TLDR
This work introduces a new probabilistic modeling strategy based on the key assumption that activity time course would be subject to uncertainty even if the parameters of the underlying dynamic process were known, which leads to a hierarchical Bayesian model which is formulated using the formalism of Probabilistic Graphical Modeling (PGM).
Deep Learning for PET Image Reconstruction
TLDR
This article reviews the use of a subdiscipline of artificial intelligence (AI), deep learning, for the reconstruction of images in positron emission tomography (PET), replacing conventional components with deep-learning data-driven alternatives, such as for the regularization.
A Kernel Density Estimator-Based Maximum A Posteriori Image Reconstruction Method for Dynamic Emission Tomography Imaging
TLDR
The results show the effectiveness of the proposed iterative reconstruction method, especially in low-count regimes, which provides better uniformity within each region of activity, significant reduction of spatiotemporal variations caused by noise, and sharper separation between different regions of activity than expectation maximization and an MAP method employing a more traditional Gibbs prior.
4D-PET reconstruction using a spline-residue model with spatial and temporal roughness penalties
TLDR
Aspline-residue based 4D-reconstruction is proposed, which describes TACs as weighted sums of convolutions of the arterial input function with cubic B-spline basis functions, and which achieved >50% improvements for five of the eight combinations of the four kinetics parameters for which parametric maps were created with the bias and noise measures used to analyse them.
A Higher-Order Polynomial Method for SPECT Reconstruction
TLDR
The proposed higher-order polynomial method for SPECT reconstruction outperforms significantly the cutting edge reconstruction method based on a traditional discrete model in terms of model error reduction, noise suppression, and artifact reduction.
Robust compartmental model fitting in direct emission tomography reconstruction
TLDR
This paper examines the robust solution of the fitting problem both in the initial phase and during the ML–EM iteration, implemented on GPUs and built into the 4D reconstruction module of the TeraTomo software.
