| titleOfInvention | A Graph Cut Algorithm-Based Method for Separating Water and Fat in Magnetic Resonance Images |
| abstract | The invention discloses a method for separating water and fat in magnetic resonance images based on a graph cut algorithm, which is characterized by comprising the following steps: (1) multi-echo data acquisition (2) preprocessing (3) calculation of the relationship between water and fat models and data Residuals, determine the candidate values of the field strength (4) use the graph cut algorithm to calculate the field map (5) calculate the water and fat images. Multiple echoes make the separation effect more accurate and robust, and the signal-to-noise ratio of water and fat images is higher; the multi-peak fat model is used, and the separation results are more accurate; the graph-cut algorithm is used to calculate the selected field strength value, avoiding the mathematical problem of phase winding , and alleviates the large-area error separation phenomenon that is prone to occur in algorithms such as region growth, and can effectively correct large-scale and large-scale magnetic field inhomogeneities. |
