\section{Image Processing Methods}  The Image processing methods consist of few pre-processing steps. Generally the volumetric magnitude image is used for masking the ROI in the phase volume. In order to do that a standard brain extraction(FSL BET) is performed and also a binary brain mask is generated. The extracted brain thus obtained is further co-registered with the MNI standard 1mm brain using FSL FLIRT and the forward and inverse transformation matrix are generated for   \subsection{Method 1}  This image processing method considers only the magnitude volume of SW images. This method is not perfect, but this gives a 'quick and dirty' way of looking into the distribution of veins in the
