Abstract

The invention concerns the generation of a physiological motion signal (such as cardiac or respiratory motion) in the context of MR using a pilot tone navigator. In particular, the invention provides a method for generating a medical data set (142), in particular an image data set, of a moving part (18) of the human or animal body, in particular undergoing a cyclical movement such as cardiac movement, comprising the following steps: • receiving a raw data signal (102) acquired by a magnetic resonance receiver coil arrangement (28), • separating a magnetic resonance signal (106) and a movement signal (126) from the raw data signal, • automatically assigning (126) at least two physiological phases (40, 46) of the moving body part to the movement signal (30), wherein the automatic assignment does not introduce a delay between the movement signal and the magnetic resonance signal, • automatic determination (136) and/or setting of time points (160, 170, 180) used for triggering an acquisition of the magnetic resonance signal (106) and/or for data post-processing of the magnetic resonance signal.
