(7) Reflectance spectrophotometry measurements show a drastic increase in reflectance for films annealed at 800[degrees]C compared to the as-deposited film and films annealed at up to 700[degrees]C, which is directly related to the increase in the refractive index due to film densification, rather than change in chemical structure.
A range of techniques have been developed and used to quantify these gastrointestinal perfusion abnormalities The following techniques have been used to study gastrointestinal perfusion in humans, tonometry, laser Doppler flowmetry, reflectance spectrophotometry, near-infrared spectroscopy, orthogonal polarisation spectral imaging indocyanine green clearance, hepatic vein catheterisation and measurements of plasma D-lactate.
