Data 2021, 8, 36. [ Google Scholar] [ CrossRef] All these virtual techniques are based on the 3D characterization of the object (e.g., skull, mandibles, or any other skeletal part preserved as a fossil or footprints and burrow casts) subject to analysis ( Knaust, 2012; Kouraiss et al., 2019). This could be also done to digitize solely the external surface of the object (e.g., using laser scanning, modulated-light, structure-light surface scanning or photogrammetry) or to digitize both the external surface as well as the internal structures with XCT ( Kouraiss et al., 2019) or synchrotron microtomography (SRμCT) ( Sanchez et al., 2012; Davesne et al., 2019; Honkanen et al., 2020). Depending on the type of the object and the aim of the study, the resolution required will be different, and therefore, one type of tomography will be used. For those studies of large- or medium-sized specimens, the use of medical XCT system is appropriate. However, for other studies that require more level of resolution (e.g., those based on cranial sutures, roughness of muscle insertions, crown dental topology, or other tiny bone elements such as the anatomy of the trabeculae), the use of laboratory XCT system and XμCT system will be recommended. On the other hand, to study cellular elements such as osteocytes or other components of cellular size, the use of synchrotron (SRμCT) is recommended. However, these sources are still difficult to access because of competitiveness for access and large technological size, increasing also the costs of their use. On the other hand, the use of computed tomography of neutron sources (nCT) is recently having great acceptance in the scientific community, as it has a resolution comparable to that of a μCT. However, nCT has the same disadvantages as SRμCT relative to use, economic cost, and time. Moreover, as it is a very recent technique, with very few institutions having this technology, access to nCT is much more competitive than to μCT or SRμCT. Despite this, the advantages of using nCT are greater than their limitations. For example, its use does not disrupt organic matter preserved in fossils (DNA, RNA, or proteins) compared to SRuCT ( Lakey, 2009; Immel et al., 2016), as nCTs are based on very low neutron energies with high penetration power due to their low interaction with matter ( Tremsin et al., 2015). The other advantage is that it is possible to obtain high contrasts of internal structures in fossil samples – contrary to that of X-rays – especially to distinguish between mineralized tissues (fossil entity) and matrix. This is due to the great penetration capacity with very low neutron attenuation ( Schwarz et al., 2005; Sutton, 2008; Schillinger et al., 2018; Zanolli et al., 2020).

In this contribution, we developed a planning prototype for 3D cranial implants within the freely available medical research platform MeVisLab ( http://www.mevislab.de/) [ 18]. To the best of our knowledge, this is the first time cranioplasty has been introduced to the MeVisLab platform. We decided for the semi-commercial platform MeVisLab, because it is currently more stable and user friendly than the pure open source platforms, like Slicer or the two MITK toolkits ( www.mitk.org/ and http://www.mitk.net/ from Germany and China). In summary, our method uses the mirrored skull as a template for generating a good fitting and aesthetic looking implant. Fitting in terms of no gaps between the bone and the implant. However, since surgeons have an interest in modifying the implants individually to a certain level, we did not design a fully-automated system performing all operations without any user interaction. Rather, the user can manually intervene in every step for specific modifications of the implant. Finally, the implant model can be stored as STL file to be used with 3D printing technology [ 19]. As audience for this contribution, we want primarily to target clinical/biomedical end users of our prototype. However, we also try to target researches that may want to build upon our solution. Thus, we also provide a more detailed technical description and code-sections like the paragraphs concerning the "Smoother module". We hope that the technical description makes it easier to understand the network/module and enables extensions for further features. Chun, H.J.; Yi, H.J.

[ Google Scholar] [ CrossRef] In any acquisition from XCT systems, various artifacts may appear because of physical problems of the object, such as (i) a high density of the material, (ii) an excessive size of the object for the limits of the scanning envelope of the machine, and (iii) displacement of the object during the acquisition process or due to the inaccurate calibration of the machine (i.e., the parameters of acquisition used). Accordingly, the first step to follow is to review and to calibrate the images obtained to eliminate artifacts. Ridgway, E.B.; Weiner, H.L. Skull deformities. Pediatr. Clin. N. Am. 2004, 51, 359–387.
