The classic maximum-likelihood estimation and predicted point spread function method with signal-to-noise ratio 3 was used with a constant background across all images from the same channel on the same day.
The marker tracking method is robust and the maximum geometric bias was voxels while the error due to noise remains below 0.1127 voxels for Rician noise distributions with signal-to-noise ratios from 5 up to 35.
We applied a stringent filter criterion including signals with signal-to-noise (SNR) ratios above 10.
If two or more consecutive spots in an LC run with precursor m/ z were within 200 ppm tolerance, the spot with the maximum signal-to-noise ratio was subjected to tandem MS analysis.
In both studies, quantitative analysis revealed nearly identical signal intensity/time (SI/T) curves with no differences noted in terms of maximal relative signal drop, full width half maximum or signal-to-noise ratio of the concentration curve at maximum concentration.
Self-quenching was found to limit the maximum signal-to-noise ratio achievable with Sm3 +, Dy3 +, Er3 + and Tm3 + activators, which was not the case for Eu3 + in the 1 10 mol% range.
With the weights, we obtain the maximum signal-to-noise ratio of the combined signal as the sum of the signal-to-noise ratios of the received signals (9).
This means that, uniquely among current pure shift methods, PSYCHE allows the experimenter to control the compromise between sensitivity and spectral purity, by adjusting the value of β to give the maximum signal-to-noise ratio compatible with the required degree of freedom from spectral artefacts.
These schemes are derived from the maximum signal-to-noise ratio (MaxSNR), also known as maximum carrier to interference ratio (MaxC/I), technique which allocates the resource at a given time to the active mobile with the greatest SNR.
Compared with a human head coil at 9.4 T, the maximum Signal-to-Noise ratio (SNR) was increased by a factor of about five in the peripheral cortex.
