WebMay 14, 2024 · Signal-to-noise ratio ( SNR) is a generic term which, in radiology, is a measure of true signal (i.e. reflecting actual anatomy) to noise (e.g. random quantum mottle). On MRI the signal-to-noise ratio is measured frequently by calculating the difference in signal intensity between the area of interest and the background (usually … WebThe necessary temperature difference between the rotor blade and the flow only relies on the absorbed solar radiation, which often leads to a low signal-to-noise ratio. Furthermore, a large distance of up to 400 m exists between the rotor blade and the thermographic camera for ground based measurements, mainly due to the height of the wind turbine.
