- The sample task names LCTSC-Train-S1-001, credits LCTSC under CC BY 3.0, and reports edge and overlap scores.
Field notes
The sample screen identifies a heart task on axial slice 49 of 140 and names the scan LCTSC-Train-S1-001, with LCTSC and CC BY 3.0 credited. The described review loop overlays a reference contour and directs users to slices with the largest disagreements. The page says scoring runs in the browser and explicitly warns that the game is not a medical device and is not for clinical use.
