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.
