Simultaneous metabolic and oxygen imaging is promising to follow up therapy response, disease development and to determine prognostic factors. FLIM of metabolic coenzymes is now widely accepted to be the most reliable method to determine cellular bio

Publikováno v: Multiphoton Microscopy in the Biomedical Sciences XX.

We describe a metabolic-imaging system based on simultaneous recording of lifetime images of NAD(P)H and FAD. The system uses two-photon excitation by a dual-wavelength femtosecond fibre laser. The two wavelengths of the laser, 780 nm and 880 nm, are

Publikováno v: Neuroimage

A major methodological challenge of functional near-infrared spectroscopy (fNIRS) is its high sensitivity to haemodynamic fluctuations in the scalp. Superficial fluctuations contribute on the one hand to the physiological noise of fNIRS, impairing th

We robustly and accurately estimated the absorption coefficient of the second layer in a two-layer tissue phantom by applying an optimal estimation method, including a priori information, to single-distance time-resolved measurements.

The nEUROPt protocol is one of two new protocols developed within the European project nEUROPt to characterize the performances of time-domain systems for optical imaging of the brain. It was applied in joint measurement campaigns to compare the vari
