The LIDC/IDRI Database [6, 5] consist of 1018 helical thoracic CT scans (cf. section 4). It forms the basis for our LoDoPaB-CT Dataset. We simulate the missing projection data to make the dataset WebMaterials and methods: Twenty-two patients with pulmonary emphysema underwent chest CT imaging using identical scanners with three different tube currents: 240, 120, and 60 mA. Scan data were converted to CT images using Adaptive Iterative Dose Reduction using Three Dimensional Processing (AIDR3D) and a conventional filtered-back projection mode.
