Abstract:GPU-based nonlinear model fitting optimizer called GPU-LMFit. We demonstrate the applications of GPU-LMFit in super resolution localization microscopy, fluorescence lifetime imaging microscopy, diffusion-weighted MRI (DW-MRI) and myocardial longitudinal relaxation time (T1) MRI using modified Look-Locker inversion recovery (MOLLI) based techniques. The results show that the use of GPU-LMFit can readily result in more than tens of times of speedup of parametric analyses in these techniques, compared with the so… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
