Quality assurance of 3D-printed patient specific anatomical models: a systematic review

3D Printing in Medicine

Table 10 total error (SegE+DEE + PrE) evaluation. Publications according to the combinations of subcategories of the segmentation error (describing methods for measuring the original structures and setups of image acquisition) and the printing error (describing methods for measuring the printed model). All combinations found in the literature are listed. Combinations no publications could be assigned to are not shown

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)
