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.
