Virtual reality simulations in medicine present a variety of technical challenges that differ from those associated with flight, space, and battlefield simulations. One imposing barrier to the widespread adoption of medical simulators is the lack of software tools that could enable medical content developers to author simulations in their respective disciplines. Our experience in developing custom standalone virtual reality applications in medicine has provided the basis for the development of Teleos™, a software toolkit for authoring interactive simulations in medicine.
A project is described (The Visible Embryo Project) to develop software strategies for the creation of large-scale databases of 3-dimensional image data on human developmental anatomy. The issues discussed relate to the processing of serial-section image data for the purpose of reconstructing volumetric models of individual embryos from museum specimens. Attempts were made to fully automate the processes of image registration and artifact correction, in order to allow for the eventual unattended reconstruction of thousands of such embryos from such resources as the Carnegie Collection of Human Embryology. Tools were also developed to allow the real-time interactive visualization of the massive databases that this type of reconstruction project creates. The implementation of a 3-D model of a human embryo in a viewer-centric virtual reality environment is also described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
