Abstract We propose a complete framework for Bayesian image reconstruction and uncertainty quantification based on a Gaussian process prior (GPP) to overcome limitations of maximum likelihood expectation maximization (ML-EM) image reconstruction algo

Abstract Targeted radiopharmaceutical therapy with alpha-particle emitters (αRPT) is advantageous in cancer treatment because the short range and high local energy deposition of alpha particles enable precise radiation delivery and efficient tumor c

In our previous work on image reconstruction for single-layer collimatorless scintigraphy, the min-min weighted robust least squares (WRLS) optimization algorithm was proposed to address a general reconstruction problem in which both the system matri
