Visualization of medical data in three-dimensional (3D) or two-dimensional (2D) views is a complex area research. In many fields 3D are used to understand the shape an object, and 2D spatial relationships. It unclear how 2D/3D play role field. Using can potentially decrease learning curve experienced with traditional by providing whole representation patient's anatomy. However, there challenges compared 2D. This current study expands on previous evaluate mental workload associated both...
We describe the use of virtual reality technology for surgical planning in successful separation thoracopagus conjoined twins. Three-dimensional models were created from computed tomography angiograms to simulate patient's anatomy on a stereoscopic display. Members teams reviewed anatomical localize an interatrial communication that allowed blood flow between two hearts. The plan close 1-mm was significantly modified based pre-procedural spatial awareness presented visualization. display...
We present Bento Box, a virtual reality data visualization technique and bimanual 3D user interface for exploratory analysis of 4D ensembles. Box helps scientists engineers make detailed comparative judgments about multiple time-varying instances that up ensemble (e.g., group 10 parameterized simulation runs). The approach is to an organized set complementary volume visualizations juxtaposed in grid arrangement, where each column visualizes single instance row provides new view the from...
Advancements in medical image visualization recent years have enabled three-dimensional (3D) images to be volume-rendered from magnetic resonance imaging (MRI) and computed tomography (CT) scans. Medical data is crucial for patient diagnosis education, analyzing these models rather than two-dimensional (2D) slices would enable more efficient analysis by surgeons physicians, especially non-radiologists. An interaction device that intuitive, robust, easily learned necessary integrate 3D...
The purpose of this research was to understand how measurements the aging body change in seated and standing positions. An integrated approach taken select appropriate 3D scanning technology, develop a landmarking method, position analyze waist–hip–thigh region. Each part method developed enable an in-depth analysis circumference shape change, including expansion contraction across different postures. New methods quantify diverse bodies can improve product fit create inclusive, quality...
The purpose of this research was to explore new methods 3D scanning, body postures, and landmarking techniques complete in-depth analyses skin deformation, measurement change, shape change the waist-hip-thigh region body.There is a need develop test integrated using 1D, 2D, data quantify how where changing in different postures.An approach taken select appropriate scanning technology, method, position analyze region.A convenience sample 11 women participated pilot study, ranging age from...
The dramatic rise of digital medical imaging has allowed personnel to see inside their patients as never before. Many software products are now available view this data in various 2D and 3D formats. This also raises many basic research questions on spatial perception for humans viewing these images. work presented here attempts answer the question: How would adding stereopsis depth cue affect relative position tasks a context? By designing conducting study isolate benefits between monoscopic...
Advances in technology are making virtual reality (VR) available for many different interests. Inexpensive commercially hardware can be setup at home [1,2], while corporations using VR to design mechanical systems and train pilots [3,4]. However, limited application is seen the medical field.
Graphics technology has extended medical imaging tools to the hands of surgeons and doctors, beyond radiology suite. However, a common issue in most software is added complexity for non-radiologists. This paper presents development unique toolset that highly customizable targeted at general physicians as well specialists. The core functionality includes features such viewing images two-and three-dimensional representations, clipping, tissue windowing, coloring. Additional can be loaded form...
Physical activity can lead to the displacement of female breasts causing psychological and physical discomfort or even breast pain. It is suggested for all exercising females protect with additional support restriction against displacement. The purpose this research was introduce use 4D scanning technology understand shape in motion. Twenty-six participants who identified themselves as wearing Missy Size 18 were recruited scanning. Three most common bust measurements tracked dynamic states...
Despite the complexity of human hand, most large-scale anthropometric data for hand includes minimal measurements. Anthropometric studies are expensive and time-consuming to conduct, more efficient methods needed capture build civilian databases impact product design factors analyses. A first its kind 3D database was result this study with 398 unique datasets. This created at cost time researchers improve accessibility products hands.
Scientific visualization tools are rapidly embracing the necessary challenge of simultaneously visualizing multiple parameterized simulation data sets [8]. In new paradigm, scientists hope to understand parameter relationships and stochastic trends that exist in a space [6], [7]. At same time, virtual reality (VR) environments have enabled exciting possible opportunities for exploring comparing time varying spatial [3]. Although VR offers unique perspective view 3D 4D data, it requires high...
Legg-Calvé-Perthes disease (LCPD) is a painful pediatric hip condition caused by an idiopathic disruption of blood flow to the femoral head. The bone subsequently becomes necrotic and fragile. This can result in significant head deformity, leading pain early degeneration hip. Severity avascular involvement correlates with long-term outcomes, including arthritis replacement. Preclinical models present extreme cases do not represent spectrum LCPD seen clinically. A virtual model was developed...
Abstract Extended reality tools have been theorized to revolutionize medicine. Many on the market today fail provide value in a clinical setting. must emulate existing workflows add doctor’s process. A framework is created capture workflow by defining user tasks, graphical interface functionalities and backend software functionalities. Two extended tool designs are presented based captured framework. The first designed for communication collaboration, while second with full immersive experience.
