CT Scans of Medieval Fragments In Early Modern Leather Bindings

3D images stored as NIfTI files for CT scans of book spines. 

Three scanned books are labeled as SJEE1, SJEE2, and SJEE3. 

CT scan of each book is stored as 6 segments. 

3D NIfTI image can be viewed by medical image viewing software such as 3D Slicer (, ITK-SNAP (, and MRIcor (  

The images can be downloaded from OneDrive here: NIfTI
