Spatial Analysis of Movement Patterns in Operating Rooms
Thursday, December 03, 2015
Category: Webinars

Surgical workflow monitoring and analysis in the operating room promote safe and efficient surgical operations through developing context sensitive operating rooms, evaluating and training surgical staffs, optimizing surgeries and generating automatic reports. This webinar presents a study on analyzing movement patterns of surgical staff to recognize contexts during neurosurgical operations. We collected movement data by video recording and an ultrasonic location aware system from 10 neurosurgery cases. We extracted movement characteristics using an optical flow algorithm and trajectory-based clustering techniques. Then we applied a Support Vector Machine to the extracted patterns to examine the intraoperative context recognition rate.

Presenter: Atsushi Nara is an Assistant Professor in the Department of Geography at San Diego State University, where he is also an Associate Director at the Center for Human Dynamics in the Mobile Age.
