| titleOfInvention | A Method of Water and Fat Separation in Magnetic Resonance Image Based on Graph Cut Algorithm |
| abstract | The invention discloses a magnetic resonance image water-fat separation method based on a graph-cut algorithm, which is characterized in that it comprises the following steps: (1) multi-echo data acquisition (2) preprocessing (3) calculation of water-fat model and data Residual error, determine the candidate value of the field strength (4) Use the graph cut algorithm to calculate the field map (5) Calculate the water and fat image. Multiple echoes make the separation effect more accurate and robust, and the signal-to-noise ratio of water and fat images is higher; using the multi-peak fat model, the separation result is more accurate; using the graph cut algorithm to calculate the selected field strength value, avoiding the mathematical problem of phase winding , and alleviate the large-scale error phenomenon that is easy to appear in the region growing algorithm, and can effectively correct the large-scale and large-scale magnetic field inhomogeneity. |
