Abstract
The application relates to the problem of navigating a surgical instrument (at 301, 311) towards a region-of-interest (at 312) in endoscopic surgery when an image (300) provided by the endoscope is obscured at least partly by obscuring matter (at 303), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation. To address this problem, a computer-implemented method is proposed, wherein, upon detecting that the image from the endoscope is at least partly obscured, a second image is determined based on a sequence of historic images and based on the current position and orientation of the endoscope. Furthermore, a virtual image (310) is generated based on the determined second image.
