Ultra-low-illumination, high-fidelity longitudinal monitoring of cerebral perfusion via deep learning-enhanced laser speckle contrast imaging
This paper introduces TunLSCI, a deep learning-based framework that reconstructs high-fidelity cerebral blood flow images from ultra-low-illumination laser speckle contrast data, thereby reducing phototoxicity by approximately 157-fold and enabling stable, long-term longitudinal monitoring of cerebral perfusion in vivo.
