Automated Segmentation of Coronary Arteries

Post Challenge Data Access:

Thank you for your interest in this data.The dataset of CTCA images and segmentation used for the ASOCA challenge is available on the UK Data Service.

We also have a temporary form to request access on an alternative platform in case of issues with the UK Data Service.

Data

You are provided with a training set of 40 Cardiac Computed Tomography Angiography (CCTA) with contrast agent showing the coronary arteries, comprising of 20 healthy patients and 20 patients with confirmed coronary artery disease. Annotations produced by three expert annotators are provided for this training set.

Further 20 CCTA images (10 healthy and 10 patients with disease) will be released as the test set used for evaluation of the segmentation algorithms. Ground truth for the test set will not be provided while the challenge is in progress.

Task

The task of this challenge is to segment the coronary artery lumen; not including calcified regions or other disease present. The developed methods must be fully automatic. Dice score and 95% Hausdorff distance will be used to evaluate the produced results.

Rules:

Refer to the detailed challenge description.

Results:

The top 10 participants will presesnt their results at MICCAI 2020, 8th October 2020: (09:00-13:00 UTC )
