  Aorta provides the main blood supply of the body. Screening of aorta with
imaging helps for early aortic disease detection and monitoring. In this work,
we describe our solution to the Segmentation of the Aorta (SEG.A.231) from 3D
CT challenge. We use automated segmentation method Auto3DSeg available in
MONAI. Our solution achieves an average Dice score of 0.920 and 95th percentile
of the Hausdorff Distance (HD95) of 6.013, which ranks first and wins the
SEG.A. 2023 challenge.
