Abstract

A system and method for augmenting an endoscopic display during a medical procedure including capturing a real-time image of a working space within a body cavity during a medical procedure. A feature of interest in the image is identified and an overlay is displayed on the image marking the feature. Computer vision is used to detect in real time changes in the image that are indicative of the feature of interest being at least partially obscured. In response to such detected changes, a quality of the overlay is altered, e.g. to make it more bright or opaque, based on the change in visibility of the feature of interest in the image.

Claims (24)

1. A method of augmenting an endoscopic display during a medical procedure, the method comprising:

positioning a camera in a working space within a body cavity and using the camera to capture real-time images of the working space during a medical procedure;

displaying the image on an endoscopic display;

receiving real-time user input identifying an anatomical feature of interest in the image displayed on the endoscopic display;

displaying an overlay on the endoscopic display, the overlay marking the feature of interest;

detecting in real-time a decrease in the visibility of the feature of interest within the image during the medical procedure, the decrease indicative of the feature of interest becoming at least partially obscured by smoke or pooling blood; and

altering a quality of the overlay to enhance the visibility of the overlay marking the feature in response to the detected decrease.

2. The method of claim 1 in which the detecting step detects, on the captured image, an edge of a pool of blood or a volume of smoke in the body cavity positioned to at least partially obscure the feature of interest.

3. The method of claim 2 in which the detecting step detects an edge of a pool of blood.

4. The method of claim 2 in which the detecting step detects an edge of a volume of smoke.

5. The method of claim 1 in which the detected decrease that is indicative of the feature of interest becoming at least partially obscured is a change in image contrast.

6. The method of claim 5 in which the change in image contrast is a local change in the region of the feature of interest.

7. The method of claim 5 in which the detecting step detects a change in overall contrast on the image.

8. The method of claim 1 in which the detected decrease that is indicative of the feature of interest becoming at least partially obscured is a change in image color.

9. The method of claim 8 in which the change is a change in local image color in the region of the feature of interest.

10. The method of claim 8 in which the change is a change in overall color of the image.

11. The method of claim 1 in which the detected decrease indicative of the feature of interest becoming at least partially obscured is a change in image texture.

12. The method of claim 1 , wherein the overlay has an opacity, and wherein altering the quality includes changing the opacity of the overlay based on the visibility of the feature in the image.

13. The method of claim 12 , wherein the opacity is increased as the feature becomes less visible.

14. The method of claim 1 , wherein the overlay has a color, and wherein altering the quality includes changing the brightness of the color based on the visibility of the feature in the image.

15. The method of claim 14 , wherein the brightness is increased as the feature becomes less visible.

16. The method of claim 1 , further including delivering an alert to the user in response to the detection of the change.

17. The method of claim 16 , wherein the alert is a haptic alert.

18. The method of claim 16 , wherein the alert is an auditory alert.
