Matrix Gradient Coil: Current Research Status and Perspectives

doi:10.11938/cjmr20202812

Abstract

Abstract: The performance of gradient and shim coils affect the quality of magnetic resonance imaging (MRI) directly. Conventional gradient/shim coils have some inherent disadvantages, such as the state of produced magnetic field is single and inflexible, many types of coils are required and the structure is complex, while the matrix gradient coils are able to overcome those problems. This paper introduces the concept and characteristics of matrix gradient coil, and reviews the current progresses in this research topic according to the structure and function of the gradient coil. The development tendency of matrix gradient coil in the future is proposed. In addition, the preliminary research on matrix gradient coil is presented.

Key words: magnetic resonance imaging (MRI), matrix gradient coil, multi coil, gradient, shim
