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. clippointid1.csv: PointID of clvein1.vtp at which to clip PV1 clippointid2.csv: PointID of clvein2.vtp at which to clip PV2 clippointid3.csv: PointID of clvein3.vtp at which to clip PV3 clippointid4.csv: PointID of clvein4.vtp at which to clip PV4 clvein1.vtp: Centerline of PV1 clvein2.vtp: Centerline of PV2 clvein3.vtp: Centerline of PV3 clvein4.vtp: Centerline of PV4 gt_noclip_mesh.vtp: Surface mesh extracted from gt_noclip.mhd gt_noclip.mhd + gt_noclip.zraw: Labeled image representation of GT gt_std_mesh.vtp: Surface mesh after standardisation gt_std.mhd + gt_std.zraw: Image representation of GT with labels copied from gt_std_mesh.vtp image.mhd + image.raw: Image to segment mitralplane.csv: Point, normal, and insideout flag describing mitral plane location
