Objective: Augmented reality (AR) has been recently applied in endoscopic surgery [1, 2]. In AR a virtual object is superimposed on a real scene to enhance the information from the real scene. In AR applied to endoscopic surgery, a 3D virtual model of human organs reconstructed from CT or MRI images are superimposed on the endoscopic video. However, to our knowledge, there is no web based platform which can provide AR for surgical use. This work presents a web application which can display a superimposed view of an endsocope live video and a 3D virtual model of human torso phantom.
Results: A 3D virtual model (Fig. 1) of human torso phantom (IOUSFAN, Kyoto Kagaku Co. Ltd., Kyoto, Japan), was reconstructed from its CT scan. An endoscope system of Karl Storz R was used for video input (Fig. 2). The application was run in several kinds of web browser(such as mozilla firefox and google chrome) to visualize the 3D model, endoscope video and their combined view (Fig. 3). The endoscope video can be displayed in real-time.
Conclusion: A web application to visualize superimposed endoscope video and 3D virtual model was developed. This is an initial step towards developing a web application for augmented reality which can be used by clinicians. The current application would be further developed to include a image based camera tracking system. The complete system would further be analyzed for its tracking accuracy.
