Method and system for recognizing and assessing surgical procedures from video

摘要

A Method and System For Recognizing and Assessing Surgical Procedures from a video or series of still images is described. Evaluation of surgical techniques of residents learning skills in areas such as cataract surgery is an important aspect of the learning process. The use of videos has become common in such evaluations, but is a time consuming manual process. The present invention increases the efficiency and speed of the surgical technique evaluation process by identifying and saving only information that is relevant to the evaluation process. Using image processing techniques of the present invention, an anatomic structure of a surgical procedure is located on a video, timing of predefined surgical stages is determined, and measurements are taken from frames of the predefined surgical stages to allow the performance of a surgeon to be assessed in an automated and efficient manner.

主权项

1. A computer-based method for recognizing and assessing surgical procedures captured on a digital video having a plurality of frames, the method comprising the steps of:
providing surgical procedure video data on a computer having a processor, memory and computer readable media and storing said input video data on the computer readable media; locating in the surgical procedure video data on the computer an anatomic structure of a surgical procedure; determining in the surgical procedure video data on the computer timing of predefined surgical stages; determining on the computer a plurality of measurements from frames of the predefined surgical stages separated by the timing; determining the timing by using a classifier; identifying on the computer action frames where the surgeon is performing actions on the anatomic structure; identifying on the computer downtime frames in which the surgeon is not performing actions on the anatomic structure; retaining on the computer the action frames while discarding the downtime frames; and assessing performance of a surgeon responsible for the surgical procedure according to the determined measurements.
