Training Subset — Unannotated (Original 3D LSM Images)

The training set with no annotation for self-supervised learning are the original 3D LSM images where the unannotated patches in Task 1 come from. This set contains a total of 66 large 3D LSM images.

Isolated Structures (30 images, each exceeding 4×1010 voxels, amounting to over 44,000 patches)

Structure TypeImages
c-Fos+ cells [1]18
Cell nuclei [2]4
Amyloid-beta plaques [3]4
Chondrocytes [4]1
Chondrogenic cells [4]1
Dopaminergic neurons [5]1
Astrocytes [5]1

Contiguous Structures (36 images, each exceeding 3×1010 voxels, amounting to over 40,000 patches)

Structure TypeImages
Blood vessels [6]9
Arteries [7]4
Sympathetic nerves [7]4
Peripheral nerves (PGP9.5) [4, 5, 7, 8]5
Lymphatic vessels [7]4
Cranial nerves [4, 5]2
Axonal markers [9]8

Annotated Training, Preliminary Test & Final Test Sets

The annotated cases in the training, preliminary test, and final test sets are the same as in Task 1. Please refer to the Dataset for Task 1 page for full details.
