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 a particular ROI. The extracted magnitude brain does show the veinous arrangements but it is dificult to segment it out, because the veins appear black in the magnitude image with not so good contrast with surrounding tissues.   \begin{itemize}  \item \textbf{Processing Step \textbf{Step  1}: \item \textbf{Processing Step \textbf{Step  2}: \end{itemize}
