Intensity non-uniformity correction in MRI: Existing methods and their validation [ J ]. Medical Image Analysis,2006,10(2) :234-246.Belaroussi B, Milles J, Carme S, Zhu YM, Benoit-Cattin H. Intensity non-uniformity correction in MRI: existing methods and their vali- dation. Med Image ...
The correction of intensity non-uniformity (INU) in magnetic resonance (MR) images is extremely important to ensure both within-subject and across-subject reliability. Here we tackled the problem of objectively comparing INU correction techniques for T1-weighted images, which are the most commonly ...
Moreover, the evaluation of NUC algorithms is not straightforward because the true amount of non-uniformity in MRI images is unknown, and it is therefore not possible to directly measure the accuracy of the non-uniformity correction. Comparisons of NUC methods have been reported using simulated ...

was to explore the analysis of temporal hpfs. a new non-uniformity correction method called bilateral filter based temporal high-pass filter (bfth) was proposed. the main properties of the hpf developed in this study were convergence speed and ghosting artifacts. through comparison between ...

Moreover, a correction coefficient,η, of the global flux was introduced. This coefficient was calculated considering the real distribution of the electrons, which had a larger effective diameter DE than the nominal focus beam diameter, as shown in the Monte Carlo simulations. DE was calculated ...
correction of the beam shape may be used, for example other cylindrical optics with an apodizing aperture. The double-grating spectral disperser 12 utilizes grating 1 to disperse the spectrum while grating 2 recollimates the beam so that it has a generally rectangular form as shown at B (...
