Abstract
Disclosed is a method and system for designing a magnetic resonance imaging permanent magnet, a device, and a medium. The method includes: obtaining a target magnetic field map of a target magnetic block set, and the target magnetic block set is a set of target magnetic blocks corresponding to a number of target magnetic blocks determined based on a total mass of a set magnet; inputting the target magnetic field map into a parametric model to obtain a parameterized matrix, where the parameterized matrix includes a candidate spatial position number of each target magnetic block, spatial position coordinates of a center of each target magnetic block, an angle of each target magnetic block, and material distribution of each magnetic block, and the parametric model is constructed based on a deep neural network; and determining a three-dimensional spatial structure and material distribution of a permanent magnet based on the parameterized matrix.
