| titleOfInvention | A passive shimming optimization method for superconducting magnetic resonance magnets based on sequential quadratic programming |
| abstract | This application proposes a passive shimming optimization method for superconducting magnetic resonance magnets based on sequential quadratic programming and its application. The value of the magnetic field contribution of each measurement point constructs a sensitivity matrix. The dimension of the sensitivity matrix is the number of measurement points x the number of shim boxes. The shim area is located in multiple shim discs, each consisting of multiple shim boxes. , each shimming box is used to place ferromagnetic materials; a mathematical model is established based on the sensitivity matrix and the peak-to-peak field inhomogeneity of the magnetic field after passive shimming; the mathematical model is optimized by the sequential quadratic programming algorithm, so that the magnetic field in the mathematical model Uniformity is optimized to a minimum. The present application can further improve the uniformity of the static magnetic field and consume less total mass of iron pieces. |
