Signal-to-Noise Measurements in Magnitude Images from NMR Phased Arrays
A method is proposed to estimate signal-to-noise ratio(SNR) values in phased array magnitude images, based on a region-of-interest (ROI) analysis. It is shown that the SNR can be found by correcting the measured signal intensity for the noise bias effects and by evaluating the noise variance as the...
