A novel passive shimming optimization method of MRI magnet based on a PSA-SQP hybrid algorithm

In Magnetic Resonance Imaging (MRI), achieving a highly uniform main magnetic field (B 0 ) is essential for producing detailed images of human anatomy. Passive Shimming (PS) is a technique used to enhance B 0 uniformity by strategically arranging shimming iron pieces inside the magnet bore. Traditio...
