Left Atrial Segmentation Challenge 2013: MRI testing

This fileset is associated with the Left Atrial Segmentation Challenge 2013 (LASC'13). LASC'13 was part of the STACOM'13 workshop, held in conjunction with MICCAI'13. Seven international research groups, comprising 11 algorithms, participated in the challenge.

Benchmark for Algorithms Segmenting the Left Atrium From 3D CT and MRI Datasets. IEEE Transactions on Medical Imaging, 34(7):1460–1473, 2015.The challenge is also featured on http://www.cardiacatlas.org/challenges/left-atrium-segmentation-challenge/
The data and code of the challenge have been made publicly available to serve as a benchmark for left atrial segmentation algorithms. Code is hosted on https://github.com/catactg/lasc
Feel free to contact us with any questions.

This fileset consists of 20 MRI datasets for testing segmentation algorithms. Included are the ground truth segmentation and helper files for standardisation.
