In this work, we propose an automatic 3D PC-MRI segmentation of the aorta in systole using a multi-atlas approach. The evaluation done on 16 patients provide accurate automatic segmentations compared to the manual ones.
Figure 2. Cases with the highest (top) and the lowest (bottom) performance. Hausdorff map is represented as a heat map in which the regions with intense yellows represent high errors and dark or black represent errors close to or equal to zero.
Figure 1. Average performance of the method during the atlas selection process with respect to the normalized correlation coefficient metric. The similarities obtained between the target image and the warped images are ordered from the highest to the lowest, to perform the majority voting process with the best mask and add one by one the next best ones until all the images in the atlas are used.
