Oxygenation saturation. Structural and functional microvascular imaging of a nude mouse ear in vivo by OR-PAM. Upper left: structural image acquired at 570 nm; upper right: vessel-by-vessel oxygenation saturation (sO2) mapping based on dual-wavelength measurements. The arteries and veins can … Continue reading
