Problems solved by technology

However, this may not be effective as the bleeding does not stop
Therefore, surgical instruments may have to be manipulated blindly without knowledge of their position relative to the tissue

Embodiment Construction

[0078] figure 1 The basic steps of an example of a computer-implemented method for image-assisted medical applications are shown. The method includes the following steps:

[0079]In a first step S1 a first image of at least one body part of a patient is acquired, the first image being captured with an endoscope and associated with sensor data indicative of a first position and orientation of the endoscope . The first image may be received from the endoscope or from an intermediate device that forwards the first image. Alternatively, the first image may be retrieved from a storage medium.

[0080] Sensor data may be recorded by a tracking system (eg, a camera-based tracking system). The sensor data may be received from a tracking system or from an intermediary device that forwards the sensor data. Alternatively, sensor data may be retrieved from a storage medium. A camera-based tracking system may include one or more cameras that capture images from one or more positions ...

Abstract

The present application relates to the problem of navigating a surgical instrument (at 301, 311) towards a region of interest (at 312) in an endoscopic procedure when an image (300) provided by an endoscope is blurred at least partially by a blurring substance (at 303). Wherein the fuzzy substance is leaked body fluid, chippings or smoke caused by ablation. To solve this problem, a computer-implemented method is proposed in which, upon detecting that the image from the endoscope is at least partially blurred, a second image is determined on the basis of a historical sequence of images and on the basis of the current position and orientation of the endoscope. Further, a virtual image (310) is generated based on the determined second image.

Description

technical field [0001] The present invention relates to a computer-implemented method for image-assisted medical applications, a data processing system configured to perform the steps of the method, a computer program comprising instructions for causing the data processing system to execute the method, and a computer program storing such computer readable medium for a computer program. Background technique [0002] Minimally invasive procedures are usually guided by endoscopic vision. The endoscope includes a miniature camera, preferably a video camera, which allows observation of tissue in the body cavity to be treated. The visual view provided by the endoscope's camera can facilitate navigation of the instrument towards the region of interest. During handling, the visual picture provided by the camera may be blurry. For example, the visual view provided by the camera may be obscured by leaking bodily fluids (eg, bleeding from tissue resection, debris, or smoke from abla...
