The Eulerian Video Magnification approach is used in this work for color amplification of video data to offer an alternative to the conventional contact-based hardware for peripheral pulse triggering or monitoring units in MR scanners; the triggering is obtained by contactless video analysis. Two different test scenarios, one inside the scanner room of a 7T scanner and one inside the scanner bore during MR measurements at 3T, are shown. The results of the algorithm bear good resemblance with the measured pulse oximeter logs. The validation of real-time feasibility remains to be done.
