### Data Schema
|

|
136 |
The format for each generated data instance is as follows:
|
137 |
|
|
|
141 |
|
142 |
3. **image**: a 3-dimensional volumetric array (height, width, depth) of values indicating pixel intensities of MRI scan
|
143 |
|
144 |
+
4. **mask**: a 3-dimensional volumetric array (height, width, depth) of values indicating the following segmented anatomical feature(s):
|
145 |
+
|
146 |
+
- 0 = background
|
147 |
+
- 1-25 = vertebrae (numbered from the bottom, i.e., L5 = 1)
|
148 |
+
- 100 = spinal canal
|
149 |
+
- 101-125 = partially visible vertebrae
|
150 |
+
- 201-225 = intervertebral discs (numbered from the bottom, i.e., L5/S1 = 201)
|
151 |
|
152 |
+
