Simulation of endoscopy

A simulation of a biopsy. The large window shows the reconstruction of the trachea and a tumor (red). The small cylinder inside the trachea represents the endoscope. The window at the upper right shows the local view of the endoscope. The upper left window shows the CT image that is closest to the endoscope position. The simulation software provides tools for fast collision detection and automatic trajectory calculation.
Data: Two spiral CT acquisitions. Courtesy of Olivier Dourthe (CREIM Sophia Antipolis).
Segmentation: Manual segmentation of tumor and bronchi
Reconstruction: About 8000 vertices and 16000 triangles
