Physiological noise and signal-to-noise ratio in fMRI with multi-channel array coils
Sensitivity in BOLD fMRI is characterized by the signal to noise ratio (SNR) of the time-series (tSNR), which contains fluctuations from thermal and physiological noise sources. Alteration of an acquisition parameter can affect the tSNR differently depending on the relative magnitude of the physiological and thermal noise, therefore knowledge of this ratio is essential for optimizing fMRI acqui...
متن کاملOn the Definition of Signal-To-Noise Ratio and Contrast-To-Noise Ratio for fMRI Data
Signal-to-noise ratio, the ratio between signal and noise, is a quantity that has been well established for MRI data but is still subject of ongoing debate and confusion when it comes to fMRI data. fMRI data are characterised by small activation fluctuations in a background of noise. Depending on how the signal of interest and the noise are identified, signal-to-noise ratio for fMRI data is rep...
متن کاملOn Signal to Noise Ratio Tradeoffs in fMRI
When planning an fMRI experiment, it is desirable to optimize the SNR to maximize the statistical return on scan time investment. At first glance, the tradeoffs may seem unclear. As more slices are acquired, the TR needed to fit in the slices increases linearly. With longer TR the flip angle and degree of magnetization recovery between pulses both increase, leading to higher signal. However, at...
متن کاملSignal to Noise Ratio Analysis in Virtual Source Array Imaging
We consider correlation-based imaging of a reflector located on one side of a passive array where the medium is homogeneous. On the other side of the array the illumination by remote impulsive sources goes through a strongly scattering medium. It has been shown in [J. Garnier and G. Papanicolaou, Inverse Problems, 28 (2012), 075002] that migrating the cross correlations of the passive array giv...
متن کاملSignal-to-noise ratio comparison between surface coils and implanted coils.
The signal-to-noise ration (SNR) from implanted coils is widely known to be superior to that from surface coils. This article addresses the quantitative aspects of this improvement by explicitly evaluating the magnetic vector potential in a conducting medium of finite extent for both implanted and surface coils. The predictions of the model are tested with actual image data from spin warp exper...
