Patent Images

1. A method for eliminating noise in a magnetic resonance image, the method comprising:

  • obtaining a plurality of magnetic resonance images sequentially within a preset time range for a same part;

    calculating probability information relating to a probability of a first pixel and a second pixel of the plurality of magnetic resonance images belonging to a same tissue, by using decay information relating to a decay in signal intensity values for the first pixel and the second pixel according to time; and

    determining a new signal intensity value for the first pixel and the second pixel based on a weighted average of signal intensity values of the first pixel and the second pixel according to the probability information.
