Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aims to develop a CycleGAN based denoising model to enhance the quality of low‐dose PET (LDPET) images, making them as close as possible to standard‐dose PET (SDPET) images. Methods Using a Philips Vereos PET/CT system, whole‐body PET images of fluorine‐18 fluorodeoxyglucose (18F‐FDG) were acquired from 37 patients to ...

A spinodal decomposition model for the large-scale structure of the universe [PDF]
arXivThe tremendous efforts placed in understanding the structure and galaxy formation in the universe have led to major improvements in our models for the universe. Particular the computational simulations that solve its non-linear growth have painted a clearer picture of the processes behind the enormous scale and shape of the structures observed ...

Enhancing Morphological Measurements of the Cosmic Web with Delaunay Tessellation Field Estimation
The Astrophysical Journal Supplement SeriesThe density fields constructed by traditional mass assignment methods are susceptible to irritating discreteness, which hinders morphological measurements of cosmic large-scale structure (LSS) through Minkowski functionals (MFs). To alleviate this issue,

Progressive Myoclonus Epilepsy: Distinctive MRI Changes in Cerebellar and Motor Networks
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Progressive myoclonus epilepsy (PME) is a rare generalized epilepsy syndrome with a well‐characterized genetic basis. The brain networks that are affected to give rise to the distinctive symptoms of PME are less well understood. Methods Eleven individuals with PME with a confirmed genetic diagnosis and 22 controls were studied.
