BOLD Noise Assumptions in fMRI
BOLD fMRI
2009/9/8
This paper discusses the assumption of Gaussian noise in the blood-oxygenation-dependent (BOLD) contrast for functional MRI (fMRI). In principle, magnitudes in MRI images follow a Rice distribution. W...
Experimental Investigation of Angular Stackgram Filtering for Noise Reduction of SPECT Projection Data: Study with Linear and Nonlinear Filters
SPECT Projection Data Nonlinear Filters
2009/9/7
We discuss data filtering prior to image reconstruction. For this kind of filtering, the radial direction of the sinogram is routinely employed. Recently, we have introduced an alternative approach to...
RELIABILITY ANALYSIS OF TRAFFIC NOISE ESTIMATES IN HIGHWAYS OF TEHRAN BY MONTE CARLO SIMULATION METHOD
TRAFFIC NOISE ESTIMATES HIGHWAYS OF TEHRAN MONTE CARLO SIMULATION METHOD
2010/2/5
This study was aimed to examine the reliability of traffic noise estimate and measurement techniques in highways of Tehran, capital of Iran. The multiple regressions showed that the traffic flow and t...
Effects of dipole position, orientation and noise on the accuracy of EEG source localization
dipole position orientation and noise EEG source localization
2010/3/1
It was found that if the signal-to-noise ratio is above a certain threshold, localization errors in realistic head models are, on average the same for deep and superficial sources. As the noise increa...
