TL;DR: The simulation results showed the proposed iterative PVC methods provide superior performance than other existing PVC methods in terms of image quality, quantitative accuracy, and reproducibility (standard deviation), particularly for low-count data.

TL;DR: The 3D LOR-PDF approach is an effective method to generate an accurate and compact system matrix, however, when used directly in expectation-maximization based list-mode iterative reconstruction algorithms such as MOLAR, its superiority is not clear.

TL;DR: Both the simulation and experimental results show that choosing a diffuse type in either surface polishing or reflector would improve DOI resolution but degrade energy resolution, which provides useful guidance in DER DOI detector design in choosing the crystal surface finishing and DOI calculation methods.

TL;DR: The results suggest that dynamic PET with as little as 1 mCi FDG could provide discrimination between benign and malignant lung nodules with higher than 90% sensitivity and specificity for patients similar to the pilot and simulated population in this study.

TL;DR: In this paper, a high-energy ray laminated type crystal module detector is presented, which is formed by alternately arraying at least more than two strip type crystal units with different luminescence decay time along the width direction, wherein the alternate arraying method comprises alternating in one direction and alternating in two directions.
