Fluorescence Lifetime Imaging Microscopy (FLIM) Data Analysis with TIMP
Fluorescence Lifetime Imaging Microscopy (FLIM) allows fluorescence lifetime images of biological objects to be collected at 250 nm spatial resolution and at (sub-)nanosecond temporal resolution. Often ncomp kinetic processes underlie the observed fluorescence at all locations, but the intensity of the fluorescence associated with each process varies per-location, i.e., per-pixel imaged. Then t...
متن کاملEnhancing precision in time-domain fluorescence lifetime imaging.
In biological applications of fluorescence lifetime imaging, low signals from samples can be a challenge, causing poor lifetime precision. We demonstrate how optimal signal gating (a method applied to the temporal dimension of a lifetime image) and novel total variation denoising models (a method applied to the spatial dimension of a lifetime image) can be used in time-domain fluorescence lifet...
متن کاملTime-domain whole-field fluorescence lifetime imaging with optical sectioning.
A whole-field time-domain fluorescence lifetime imaging (FLIM) microscope with the capability to perform optical sectioning is described. The excitation source is a mode-locked Ti:Sapphire laser that is regeneratively amplified and frequency doubled to 415 nm. Time-gated fluorescence intensity images at increasing delays after excitation are acquired using a gated microchannel plate image inten...
متن کاملTime-domain fluorescence lifetime imaging applied to biological tissue.
Fluorescence lifetime imaging (FLIM) is a functional imaging methodology that can provide information, not only concerning the localisation of specific fluorophores, but also about the local fluorophore environment. It may be implemented in scanning confocal or multi-photon microscopes, or in wide-field microscopes and endoscopes. When applied to tissue autofluorescence, it reveals intrinsic ex...
متن کاملGPU acceleration of time-domain fluorescence lifetime imaging.
Fluorescence lifetime imaging microscopy (FLIM) plays a significant role in biological sciences, chemistry, and medical research. We propose a graphic processing unit (GPU) based FLIM analysis tool suitable for high-speed, flexible time-domain FLIM applications. With a large number of parallel processors, GPUs can significantly speed up lifetime calculations compared to CPU-OpenMP (parallel com...
