Visualization of the subcategories for the detailed analysis of applied methods. Main types of error: IAE: Image Acquisition Error, SegE: Segmentation Error, SegC: Segmentation Comparison Error, DEE: Digital Editing Error, PrE: Printing Error; basic approach: linear (lin) or surface (surf) deviation based analysis; imaging setup: experimental setups of the image acqusition: nosim: artifical model and no simulation of adjacent tissue, sim: artifical model and simulation of adjacent tissue, cad: cadaver study, pat: scan of patients due to clinical questions; tools for linear measurements: DICOM: CT-Scan of 3D-printed model and linear measurements on resulting DICOM data, cal: caliper, 3Dcal: 3D-scan and virtual linear measurements, pat: linear measurements on patient DICOM data; time of dissection (for cadaver studies): dissection is done before image acquisition (dis) or after image acquisition (nodis); could not be assigned to any of the introduced categories (other). A detailed description for each subcategory can be found in Appendix A
