Abstract

One example method for detecting phases of a surgical procedure via video processing includes accessing a video of the surgical procedure and dividing the video into one or more blocks, each of the blocks containing one or more video frames. For each of the blocks, the method includes applying a prediction model on the video frames of the respective block to obtain a phase prediction for each of the video frames. The prediction model is configured to predict, for an input video frame, one of the plurality of phases of the surgical procedure. The method further includes generating an aggregated phase prediction for the respective block by aggregating the phase predictions of the video frames, and modifying the video of the surgical procedure to include an indication of a predicted phase of the respective block based on the aggregated phase prediction.

Description

technical field [0001] This application relates generally to robotic surgery and video processing, and more specifically to the use of video processing techniques to detect surgical workflow stages and activities in surgical videos. Background technique [0002] As robotic surgery becomes more popular, a large number of surgical videos are recorded every day, especially for laparoscopic surgery. These videos contain valuable information and are an important resource for tasks such as surgical analysis and training of new surgical doctors. However, due to the large amount of surgical videos, it is infeasible for highly skilled medical professionals, a rare resource, to review long surgical videos to identify various stages of surgery and mark all meaningful events during surgery. Furthermore, it would be beneficial to discern the stage of surgery and abnormal activity during a surgical procedure so that information and warnings can be provided to the surgeon in real time or ...
