Respiration often leads to artifacts in human torso MR
images. To avoid these motion artifacts, triggered or
gated MR acquisitions are performed and a reliable
motion sensor is a necessity. Therefore a filter is
designed and tested to predict the respiration phase
real-life per k-line without time delay using thermal
noise variance of the receive array.
