The X-ray system further comprises a pilot tone system (106), wherein the pilot tone 5 system comprises a radio frequency system (108) comprising multiple transmit channel (110) and multiple receive channel (112). The multiple transmit channel is configured for transmitting multiple pilot tone signal (136) via multiple transmit coil (114). The multiple receive channel is configured for receiving pilot tone data (138) via multiple receive coil (116). Execution of the machine executable instructions causes the processor to: transmit 10 (202) the multiple pilot tone signal by controlling the multiple transmit channel; acquire (204) the pilot tone data by controlling the multiple receive channel; and determine (206) a motion state (140, 700, 700', 702, 702') of the subject using the pilot tone data.
