Magnetic tape MA-9 / GRA-7 (Inv. 2017-403)

This dataset represents the computed tomography image acquisition of a historical cipher machine from the collection of the Deutsches Museum. It is composed of CT reconstructed image stacks in the DICOM (.dcm) format.
It can be imported in any free or propietary CT-Viewer that supports the DICOM standard to generated 2D and 3D imaging.
If segmentations/ROIs are availabe, they are uploaded in a seperate image stacks and are a subset of the scanned cipher machine.
