Investigation Of Integrating Three-Dimensional (3-D) Geometry Into The Visual Anatomical Injury Descriptor (Visual AID) Using WebGL.

摘要

The Visual Anatomical Injury Descriptor (Visual AID) is a graphical computer tool developed to illustrate injury and severity on an anatomical figure, allowing for communication of trauma. Currently, the tool uses two- dimensional images rendered from three-dimensional (3-D) geometry to convey injury. While integrating 3-D geometry was a part of the initial development plan, this step was delayed while waiting for technologies to mature. This paper discusses the Web-based 3-D environment prototype being developed to understand the feasibility of integrating WebGL into Visual AID. Using WebGL will permit us to display the current anatomical geometry used by Visual AID in a 3-D Web-based environment. Employing a 3-D environment allows us to more accurately display the geometry, thus providing a better navigation system and the potential to add annotations fixed to 3-D points. Further developments must be made to better understand integration of highly detailed geometry as well as changing geometry attributes at runtime, such as Abbreviated Injury Scale (AIS) code, severity, and color association. WebGL is a novel cross-platform technology that must be further explored as standardization occurs, thus enabling future advancements. The features that have already been explored will enhance Visual AID's injury illustrating capabilities, facilitating the communication of injury data.
