Description

General information:

- This dataset contains micro-CT images and mechanical test data from ovine functional spinal units (FSU). 
- The micro-CT data was produced using a Bruker SkyScan 1172. The settings for the scans are given in the '.log' files in each folder. 
- The compression testing was conducted on an MTS 858 Mini Bionix T/II. The settings for each test can be found in test '.txt' files.
- In short, every FSU was mechanically tested in compression under different conditions. Before and after every test, the FSUs were scanned to ensure there was no damage
  to the sample. More information can be found in the related publication: 
- The mechanical testing data is arranged in folders with consecutive cycles. It is highly recommended to use the last three cycles for analysis.  

Data set notation:

- All the datasets are noted by Sheep number. Sh7 = Sheep 7; Sh8 = Sheep 8; Sh9 = Sheep 9. In the publication, the numbers were switched to 1,2,3 respectively.
- files denoted with '_rec' contain the reconstruction of the projection images. 
- 'Tested' or 'After test' files refers to the scan after mechanical testing.
