In this paper, we describe an automated process for the computer-assisted generation of sculptures that can be employed for anatomical education among the general population. We propose a workflow that supports non-expert users to generate and physically display volumetric medical data in a visually appealing and engaging way. Our approach generates slide-based, interactive sculptures-called volograms-that resemble holograms of underlying medical data. The volograms are made out of affordable and readily available materials (e.g., transparent foils and cardboard) and can be produced through commonly available means. To evaluate the educational value of the proposed approach with our target audience, we assess the volograms, as opposed to classical, on-screen medical visualizations in a user study. The results of our study, while highlighting current weaknesses of our physicalization, also point to interesting future directions.", month = sep, publisher = "Eurographics Association", issn = "2070-5786", event = "Eurographics Workshop on Visual Computing for Biology and Medicine", doi = "10.2312/vcbm.20211341", booktitle = "Eurographics Workshop on Visual Computing for Biology and Medicine", journal = "Eurographics Workshop on Visual Computing for Biology and Medicine", pages = "5", volume = "VCBM 2021", pages = "19--23", keywords = "Physicalization, Anatomy Education", URL = "https://www.cg.tuwien.ac.at/research/publications/2021/pahr-2021-vologram/", } @runphdthesis{Pahr_PhD, title = "Unknown", author = "Daniel Pahr", year = "2021", URL = "https://www.cg.tuwien.ac.at/research/publications/2021/Pahr_PhD/", } @mastersthesis{Pahr2020, title = "Vologram: Educational Craftworks for Volume Physicalization", author = "Daniel Pahr", year = "2020-22-24", abstract = "Long before the onset of computer technology, anatomical sculptures were already used for educational purposes. Digital imaging technology and its incorporation into the clinical workflow through the advancements of medical visualization led to a steady decline in the use of sculpture-based teaching aids. Currently, anatomical volume visualizations are predominantly presented on computer screens. Recent developments in augmented, mixed, and virtual reality o˙er new, exciting ways to digitally display medical imaging data. In recent years, the application of real-world sculptures to display patient imaging data has seen a resurgence through the field of data physicalization. Predominantly, it has been used to enhance the education of medical personnel and laymen through the use of physical models. Expensive 3D printing technology is often employed in the creation of high fidelity anatomical sculptures, with realistic look-and-feel. However, few approaches make use of a˙ordable physicalizations in the field of layman anatomical education. In the course of this thesis di˙erent ways to introduce self-made, custom physical-izations into layman medical education are explored. We propose a suitable concept, the Vologram, to display medical volume data in a visually appealing way for medical non-experts. This takes the form of slide-based sculptures, made out of a˙ordable ma-terials available to the general public with a high degree of interactivity, and can be produced through commonly available means. To support a customizable workflow in the creation of these sculptures, we provide a stand-alone desktop application, which allows layman users to create custom educational sculptures. Real medical imaging data can be filtered and displayed in di˙erent ways, delivering optically diverse results. We evaluate the concept in a small scale study, to determine the e˙ect of interactive medical visualizations as opposed to physicalizations on the target audience. The results of this study point to a great potential for the application of interactive educational concepts for layman anatomical education.", month = , pages = "131", address = "Favoritenstrasse 9-11/E193-02, A-1040 Vienna, Austria", school = "Research Unit of Computer Graphics, Institute of Visual Computing and Human-Centered Technology, Faculty of Informatics, TU Wien", keywords = "Phyiscalizations, Anatomy Education", URL = "https://www.cg.tuwien.ac.at/research/publications/2020/Pahr2020/", }
