Overview on the used software and hardware. Shown are the three used CT scanners (DS 2 × 64, SS 128, DS 2 × 192), the image reconstruction (FBP, 1st -, 2nd - and 3rd - generation iterative reconstruction) and the tin prefiltering technique and their combination on the time scale from 2010 to 2022 for this retrospective single-center patient study. CT = computed tomography, DS = dual source, FBP = filtered back projection, SS = single source
