Ítem Entorno para el diseño y la práctica con instrumentos quirúrgicos virtuales (WESST-IN)(Universidad Icesi, 2006-10-11) Vélez Beltrán, Jorge Alberto; Cardona, Jaime Andrés; Vera, Adriana Ximena; Navarro Newball, Andrés AdolfoThis work presents a system which allows medicine practitioners to model, to manipulate and to use virtual surgical instruments. The system allows operations like upgrade, modification and inclusion of new surgical instruments; also, it has a graphic interface which facilitates learning and an understandable help system for the final user. This tool contributes to the learning of surgical instrument manipulation for medicine students. On the other hand, the implementation of the system in a WEB environment allows its use by remote practitioners via internet.Ítem Incorporación de un módulo para la práctica de la habilidad de ubicación espacial al simulador de otorrinolaringología - WESST -OT(Universidad Icesi, 2006-10-11) Mazuera Grisales, Eduardo; Vélez Beltrán, Jorge Alberto; Gamboa , Carlos A.; Herrera Botero, Francisco Julián; Navarro Newball, Andrés Adolfo; Cardona Aristizabal, AndreaWith the development of this project, a great aide is presented to the user of the prototype «Análisis, diseño e implementación del prototipo de un entorno de práctica de habilidades quirúrgicas en Otorrinolaringología». This aide will help the user to acquire the space-anatomic positioning ability, which allows the user to associate what he sees on 2D radiological slices with what he sees through the virtual endoscope of the simulation environment. To achieve the cited ability, the user is presented with radiological images (tomography slices) with red marks that represent the current position of the endoscope he is using in the simulation environment.Ítem Entorno para el intercambio de instrumentos quirúrgicos en un simulador de otorrinolaringología WESST-ST(Universidad Icesi, 2006-10-11) Ramírez Vélez, Andrés Felipe; Roldán Correa, Fernando José; Herrera Botero, Francisco Julián; Navarro Newball, Andrés Adolfo; Vélez Beltrán, Jorge AlbertoIn this paper the development of a complementary module for the WESST - OT simulator is presented. The module allows the interchange of surgical instruments used in a nasal sinus surgery. This module was developed taking into account that in the original simulator it was possible to interact only with an endoscope and that the nasal sinus surgery requires more surgical instruments such as the Blakesley and Kerrison forceps, useful to support other techniques in addition to the orientation skill.Ítem Incorporación de la habilidad de coordinación y del módulo de personalización de sesiones al simulador de otorrinolaringología Wesst-OT(Universidad Icesi, 2007-08-01) Ramírez, Oscar Darío; Ospina C., Angélica María; Hurtado, Lina María; Herrera Botero, Francisco Julián; Castrillón S., Mauricio; Vélez Beltrán, Jorge Alberto; Navarro Newball, Andrés AdolfoThis paper describes the process of incorporating a virtual environment for the practice of the coordination skill to the Web Environment for Surgical Skills in Training in Otolaryngology, WESST - OT. Additionally, a complementary module which allows session customization and the inclusion of anomalies and pathologies in the paranasal region is presented.Ítem Anatomy guided bottom up creature skinning(Universidad Icesi, 2011-07-13T22:40:32Z) Loaiza Buitrago, Diego Fernando; Navarro Newball, Andrés Adolfo; Herrera Botero, Francisco JuliánIt is possible to guide skin construction from the creature’s inner anatomy. This paper introduces a method where is provided the system with bones, a set of muscles and a set of subsidiary organs in order to generate the mesh of the skin. The method generates a set of feature points from the inner anatomy. Then, it projects the feature points on a mirror plane which cuts the creature in the middle. Once in the plane, triangulate and reflect the points and adjust the skin’s mesh inflating it and deflating it until all skin vertices are within some threshold of the underlying anatomy. Finally, fur is generated with offsets calculated from the skin’s mesh. Feature point generation and automatic mesh generation strongly rely on the anatomical knowledge provided to the algorithm. However, it eliminates the need of a preexisting skin mesh. The resulting mesh is consistent with the underlying anatomy.
