Cipher Machine Doppel-Lochstreifenleser und Addierer T send 77 f (Inv. 1987-1)

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.

本数据集涵盖德意志博物馆（Deutsches Museum）馆藏的一台历史密码机的计算机断层扫描（CT, Computed Tomography）成像采集数据，由遵循DICOM（Digital Imaging and Communications in Medicine，.dcm）格式的CT重建图像堆栈构成。
该数据集可导入任意支持DICOM标准的免费或专有CT查看工具，以生成二维及三维成像结果。
若已提供分割标注/感兴趣区域（ROI, Region of Interest），则相关数据将以独立图像堆栈的形式上传，且为该扫描密码机的子集区域。
