Automated Delineation of Vessel Wall and Thrombus Boundaries of Abdominal Aortic Aneurysms Using Multispectral MR Images

Figure 3

Example of the texture characterization. For every landmark on the manual delineation, a 11 × 3 mm region perpendicular to the contour and centred in the landmark is defined. The pixels of the region are labelled as “interior” or “exterior” depending on their relative position with the landmark location.
