It requires vigorous training, which is difficult due to its intimate nature, leading to a need of simulation. Up until now, there are mainly models available for mere palpation which do not offer adequate visualization of the concerning anatomical structures. In this study we present a 3D printed model of the female pelvis. It can improve both the practical teaching of gynecological pelvic examination for health care professionals and the spatial understanding of the relevant anatomy. Methods We developed a virtual, simplified model showing selected parts of the female pelvis. 3D printing was used to create a physical model. Results The life-size 3D printed model has the ability of being physically assembled step by step by its users. Consequently, it improves teaching especially when combining it with commercial phantoms, which are built solely for palpation training. This is achieved by correlating haptic and visual sensations with the resulting feedback received. Conclusion The presented 3D printed model of the female pelvis can be of aid for visualizing and teaching pelvic anatomy and examination to medical staff. 3D printing provides the possibility of creating, multiplying, adapting and sharing such data worldwide with little investment of resources. Thus, an important contribution to the international medical community can be made for training this challenging examination.}, language = {en} } @article{KieselBeyersKaliszetal.2022, author = {Kiesel, Matthias and Beyers, Inga and Kalisz, Adam and W{\"o}ckel, Achim and Quenzer, Anne and Schlaiß, Tanja and Wulff, Christine and Diessner, Joachim}, title = {Evaluating the value of a 3D printed model for hands-on training of gynecological pelvic examination}, series = {3D Printing in Medicine}, volume = {8}, journal = {3D Printing in Medicine}, doi = {10.1186/s41205-022-00149-5}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-313365}, year = {2022}, abstract = {Background Simulation in the field of gynecological pelvic examination with educational purposes holds great potential. In the current manuscript we evaluate a 3D printed model of the female pelvis, which improves practical teaching of the gynecological pelvic examination for medical staff. Methods We evaluated the benefit of a 3D printed model of the female pelvis (Pelvisio®) as part of a seminar ("skills training") for teaching gynecological examination to medical students. Each student was randomly assigned to Group A or B by picking a ticket from a box. Group A underwent the skills training without the 3D printed model. Group B experienced the same seminar with integration of the model. Both groups evaluated the seminar by answering five questions on Likert scales (1-10, 1 = "very little" or "very poor", 10 equals "very much" or "very good"). Additionally, both groups answered three multiple-choice questions concerning pelvic anatomy (Question 6 to 8). Finally, Group B evaluated the 3D printed model with ten questions (Question 9 to 18, Likert scales, 1-10). Results Two of five questions concerning the students' satisfaction with the seminar and their gained knowledge showed statistically significant better ratings in Group B (6.7 vs. 8.2 points and 8.1 vs. 8.9 points (p < 0.001 and p < 0.009). The other three questions showed no statistically significant differences between the traditional teaching setting vs. the 3D printed model (p < 0.411, p < 0.344 and p < 0.215, respectively). The overall mean score of Question 1 to 5 showed 8.4 points for Group B and 7.8 points for Group A (p < 0.001). All three multiple-choice questions, asking about female pelvic anatomy, were answered more often correctly by Group B (p < 0.001, p < 0.008 and p < 0.001, respectively). The mean score from the answers to Questions 9 to 18, only answered by Group B, showed a mean of 8.6 points, indicating, that the students approved of the model. Conclusion The presented 3D printed model Pelvisio® improves the education of female pelvic anatomy and examination for medical students. Hence, training this pivotal examination can be supported by a custom designed anatomical model tailored for interactive and explorative learning.}, language = {en} } @article{LetunicBork2016, author = {Letunic, Ivica and Bork, Peer}, title = {Interactive tree of life (iTOL) v3: an online tool for the display and annotation of phylogenetic and other trees}, series = {Nucleic Acids Research}, volume = {44}, journal = {Nucleic Acids Research}, number = {W1}, doi = {10.1093/nar/gkw290}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-166181}, pages = {W242-W245}, year = {2016}, abstract = {Interactive Tree Of Life (http://itol.embl.de) is a web-based tool for the display, manipulation and annotation of phylogenetic trees.

Full interactive control over precise positioning of various annotation features and an unlimited number of datasets allow the easy creation of complex tree visualizations. iTOL 3 is the first tool which supports direct visualization of the recently proposed phylogenetic placements format.

There are three types of features in a map: point, line, and area features. Unfortunately, one cannot expect to find efficient algorithms that solve the labeling problem optimally. Interactive maps are digital maps that only show a small part of the entire map whereas the user can manipulate the shown part, the view, by continuously panning, zooming, rotating, and tilting (that is, changing the perspective between a top and a bird view). An example for the application of interactive maps is in navigational devices. Interactive maps are challenging in that the labeling must be updated whenever labels leave the view and, while zooming, the label size must be constant on the screen (which either makes space for further labels or makes labels overlap when zooming in or out, respectively). These updates must be computed in real time, that is, the computation must be so fast that the user does not notice that we spend time on the computation. Additionally, labels must not jump or flicker, that is, labels must not suddenly change their positions or, while zooming out, a vanished label must not appear again. In this thesis, we present efficient algorithms that dynamically label point and line features in interactive maps. We try to label as many features as possible while we prohibit labels that overlap, jump, and flicker. We have implemented all our approaches and tested them on real-world data. We conclude that our algorithms are indeed real-time capable.}, subject = {Computerkartografie}, language = {en} } @article{SchwarzTamuriKultysetal.2016, author = {Schwarz, Roland F. and Tamuri, Asif U. and Kultys, Marek and King, James and Godwin, James and Florescu, Ana M. and Schultz, J{\"o}rg and Goldman, Nick}, title = {ALVIS: interactive non-aggregative visualization and explorative analysis of multiple sequence alignments}, series = {Nucleic Acids Research}, volume = {44}, journal = {Nucleic Acids Research}, number = {8}, doi = {10.1093/nar/gkw022}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-166374}, pages = {e77}, year = {2016}, abstract = {Sequence Logos and its variants are the most commonly used method for visualization of multiple sequence alignments (MSAs) and sequence motifs. They provide consensus-based summaries of the sequences in the alignment. Consequently, individual sequences cannot be identified in the visualization and covariant sites are not easily discernible. We recently proposed Sequence Bundles, a motif visualization technique that maintains a one-to-one relationship between sequences and their graphical representation and visualizes covariant sites. We here present Alvis, an open-source platform for the joint explorative analysis of MSAs and phylogenetic trees, employing Sequence Bundles as its main visualization method. Alvis combines the power of the visualization method with an interactive toolkit allowing detection of covariant sites, annotation of trees with synapomorphies and homoplasies, and motif detection. It also offers numerical analysis functionality, such as dimension reduction and classification. Alvis is user-friendly, highly customizable and can export results in publication-quality figures. It is available as a full-featured standalone version (http://www.bitbucket.org/rfs/alvis) and its Sequence Bundles visualization module is further available as a web application (http://science-practice.com/projects/sequence-bundles).}, language = {en} }
