New endoscopic technique provides label-free contrast of tissue

ImageJ=1.45sunit=inch

A flexible wide-field endoscope utilising blue excitation light provides label-free contrast of tissue based on fluorescence lifetime imaging of tissue autofluorescence. Fluorescence lifetime imaging (FLIM) of tissue autofluorescence has been shown to provide labelfree contrast between different types and states of tissue. Clinical FLIM can combine lifetime contrast with morphological information to provide a direct […]
