Image-Based View Rendering in Endoscopy

摘要

Video endoscopy, a modality of minimally invasive surgery, has proven to be significantly less invasive to the patient. However, by relying on a video interface to observe the surgical scene, several nonintuitive effects need to be contended with. One of these is the reduction or removal of the discrepancy in view position and orientation between the surgeon and the endoscope. Eliminating artifacts in the visual feedback is important for the improvement of the effectiveness of the surgical procedures. This article presents a novel rendering technique to produce the scene from a "surgeon-centric" viewpoint to create greater transparency for optimizing the visual precision of the endoscopic procedures.
