Segmentation of the Vasculature from μMRI Data.

Abstract

<p>Image processing steps involved in the extraction of the 3D vasculature from the raw GE μMRI data for a 9L tumor (arrow in all panels) bearing mouse brain: (a) <i>Ex vivo</i> T₂*-weighted image corresponding to the 1^st TE; (b) Blood vessels (red) segmented out using the “tubeness” filter overlaid on the raw data in (a). (c) Binarized vasculature obtained by thresholding the tubeness data in (b) followed by removal of isolated voxels. (d) Volume rendering of the μMRI-derived vasculature, color-coded by average vessel radius.</p
