This repository contains annotated aortic centerlines and masks for 101 randomly selected images from LIDC/IDRI and aortic centerlines for 41 randomly selected images from AMOS. Aortic centerlines were annotated by placing the knots on axial, sagittal, and coronal projections, while aortic masks were annotated on every third axial slice and linearly interpolated for the rest.

The annotation was prepared for the paper [Robust Curve Detection in Volumetric Medical Imaging via Attraction Field].

We encourage the community to use the annotation to facilitate further advancements in the curves detection field.
