PreOp endoscopy simulator: from bronchoscopy to ureteroscopy.

The high cost of virtual reality simulators has posed a major obstacle to the widespread adoption of simulators for medical training. HT Medical broke through this cost barrier by developing the PreOp Flexible Bronchoscopy simulator, a realistic training simulation system that integrates force feedback, multimedia, and 3D graphics on a PC. We are currently extending the PreOp platform so that it can simulate other endoscopic procedures. This paper discusses our efforts to extend the platform to simulate flexible sigmoidoscopy and ureteroscopy.
