Time-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 کاملAngular domain fluorescence imaging for small animal research.
We describe a novel macroscopic fluorescent imaging technique called angular domain fluorescence imaging (ADFI) applicable to the detection of fluorophores embedded in biological tissues. The method exploits the collimation detection capabilities of an angular filter array (AFA). The AFA uses the principle of acceptance angle filtration to extract minimally scattered photons emitted from fluoro...
متن کاملTomographic fluorescence lifetime imaging
Fluorescence lifetime imaging microscopy (FLIM) is a well-established technique (Bastiaens and Squire 1999; Berezovska et al. 2003; Selvin 2000; Vogel et al. 2006) that combines microscopic techniques with time-resolved detection to provide high-resolution lifetime images of thin tissue sections. This chapter concerns the in vivo time domain imaging of fluorescent contrast agents embedded in de...
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 کاملFluorescence lifetime imaging ophthalmoscopy
Imaging techniques based on retinal autofluorescence have found broad applications in ophthalmology because they are extremely sensitive and noninvasive. Conventional fundus autofluorescence imaging measures fluorescence intensity of endogenous retinal fluorophores. It mainly derives its signal from lipofuscin at the level of the retinal pigment epithelium. Fundus autofluorescence, however, can...
