Prediction of the diaphragm position during imaging segments by multiple navigators and a predictor estimator during the preceding systole. The control system compares the navigator records to a model and feeds back the difference between the model and recorded value to prevent the model from diverging. This data can then be used to improve prospective slice following and increase acceptance window and increase respiratory efficiency.
