The present disclosure provides techniques for determining a respiration phase by extracting a distance characteristic value, a score characteristic value, and an area characteristic value from the respiration signal, wherein the distance characteristic value, the score characteristic value and the area characteristic value are used to indicate waveform variation between two adjacent waveforms in the respiration signal. The techniques include training a respiration signal model according to the distance characteristic value, the score characteristic value, and the area characteristic value to determine the respiration phase of the respiration signal using the respiration signal model.

Method and apparatus for determining respiration phase, magnetic resonance imaging method and system

A signal processing method including receiving an original reference radio frequency signal from a receiving antenna group; receiving the time series of the control signal associated with the transmission event of the radio frequency pulses; synchronizing the time series with the original reference radio frequency signal, and determining the echo train in the original reference radio frequency signal in a repetition time of the pulse sequence, wherein the echo train corresponds to the part of the time series associated with the transmission event of the radio frequency pulses in time sequence; setting the sampling points in the domains of the starting point and a first ending point of the echo train; and generating a fitting signal based on the sampling points to eliminate the radio frequency interference signal resulted from the transmission event of the radio frequency pulses.
