| ## BoneSegmentation Mask Channel Mapping |
|
|
| The BoneSegmentation masks are stored as 14-channel `.npy` arrays with shape: |
|
|
| ```python |
| (14, H, W) |
| ``` |
|
|
| Each channel is a binary mask for one anatomical structure. The official channel order is: |
|
|
| | Channel ID | Anatomy name | Description | |
| |---:|---|---| |
| | 0 | Capitate | Capitate bone | |
| | 1 | DistalRadius | Distal radius | |
| | 2 | DistalUlna | Distal ulna | |
| | 3 | Hamate | Hamate bone | |
| | 4 | Lunate | Lunate bone | |
| | 5 | Tri | Triquetrum / pisiform region | |
| | 6 | Scaphoid | Scaphoid bone | |
| | 7 | Trapzium | Trapezium bone | |
| | 8 | Trapezoid | Trapezoid bone | |
| | 9 | Metacarpal1st | First metacarpal | |
| | 10 | Metacarpal2nd | Second metacarpal | |
| | 11 | Metacarpal3rd | Third metacarpal | |
| | 12 | Metacarpal4th | Fourth metacarpal | |
| | 13 | Metacarpal5th | Fifth metacarpal | |
|
|
| The channel semantics are fixed across all samples. If images are canonicalized by hand side, this changes only the image orientation; it does not change the anatomical meaning of the channels. |
