“…After detailed analysis of the 3D models from each PCI step, the resultant.stl files were imported into a video game design software Unity (San Francisco, CA, USA) to create virtual reality (VR) scenes with anaglyph capabilities [14,15]. We rendered each PCI step into its own scene where a user can wear a VR headset to interact with the detailed model.…”

“…These have been uploaded on the Atlas of Human Cardiac Anatomy website as an educational resource for interventional cardiologists, students, and medical device designers. In addition, our mixed reality educational platform, composed of both VR and 3D prints, has been shown to improve learning capabilities and retention when compared to traditional single modality teaching methods [15].…”

Percutaneous coronary intervention can be a high-risk procedure that would benefit from optimizing device-tissue interactions between stents and coronary vessels. Using a perfusion-fixed human heart with coronary artery disease, we performed a percutaneous coronary intervention of the left main coronary artery bifurcation. This heart was perfused and multimodal imaging was utilized to view the procedure with direct visualization, fluoroscopy, and optical coherence tomography (OCT). We followed the European Bifurcation Club’s guidelines to perform a single-stent bifurcation before transitioning to a two-stent Culotte technique. After each procedural step, the heart was removed from the perfusion apparatus and transferred to a micro-CT scanner to obtain unique scans. We conducted apposition analyses of the computational 3D models from micro-CT DICOM datasets, and compared them to the results from direct visualization and commercial OCT’s Apposition Indicator software. Additional measurements of resulting coronary anatomic expansions were taken to determine the potential roles of each step in improving procedural outcomes. Graphical Abstract Micro-CT images show stent deformation during a percutaneous coronary intervention (provisional to Culotte bifurcation procedure) in an isolated diseased human heart.

“…Studies to examine the effectiveness of using S3D in learning anatomy includes the comparison between conventional 2D videos and 3D anaglyphic stereoscopic instruction videos in learning neuroanatomy [28,29]. Furthermore, to allow multiple students and trainees to share the learning experience, Deakyne et al [128] augmented the anatomies viewed in VR onto an external display via a custom anaglyph shader, while presenting users with anaglyph glasses. Meta-analysis for using stereopsis with 3D visual technology (3DVT) to learn anatomy was conducted by Bogomolova et al [30].…”

Three-dimensional visualization technologies such as stereoscopic 3D, virtual reality, and augmented reality have already emerged in training and education; however, light field displays are yet to be introduced in such contexts. In this paper, we characterize light field visualization as a potential candidate for the future of training and education, and compare it to other state-of-the-art 3D technologies. We separately address preschool and elementary school education, middle and high school education, higher education, and specialized training, and assess the suitability of light field displays for these utilization contexts via key performance indicators. This paper exhibits various examples for education, and highlights the differences in terms of display requirements and characteristics. Additionally, our contribution analyzes the scientific-literature-related trends of the past 20 years for 3D technologies, and the past 5 years for the level of education. While the acquired data indicates that light field is still lacking in the context of education, general research on the visualization technology is steadily rising. Finally, we specify a number of future research directions that shall contribute to the emergence of light field visualization for training and education.

“…In particular, recent studies have attempted to examine the impact of ICT on mnemonic processes such as working memory (Dahlin et al, 2008;Jaeggi et al, 2008;Karbach & Kray, 2009;Katoni, 2021). Some of these approaches have produced promising results (Deakyne et al, 2021;Foroughi et al, 2016;Oliveira. et al, 2016;Simons et al, 2016;van der Maas & Nyamsuren, 2017).…”

The aim of this study was to examine the role of virtual environments in visual recognition. A classic and economically accessible technique was chosen: anaglyph. A battery of images that differed in their emotional charge was developed. The emotional valence of the new stimulus was evaluated using the SAM battery. 2D and anaglyph modalities were also tested. 32 subjects participated in the first study and 42 subjects in the recognition task. The results: i) Participants were more accurate in classic 2D environments compared to 3D, ii) participants were more efficient in the negative 3D condition compared to the rest of the emotional conditions in this category, while the neutral environment was the most efficient for 2D. It is suggested that coding information would be simpler for a 2D stimulus, however, effects as robust as emotional charge would manifest more clearly in a deeper presentation.
