Systems and methods for performing concomitant field corrections in magnetic resonance imaging ('MRI') systems that implement asymmetric magnetic field gradients are provided, in general, the systems and methods described here can correct for the effects of concomitant fields of multiple orders, such as zeroth order, first order, and second order concomitant fields.

Systems and methods for concomitant field correction in magnetic resonance imaging with asymmetric gradients

A method for three-dimensional parallel magnetic resonance imaging (MRI) using an MRI system is provided. The method includes determining in-plane acceleration factors that optimize a selected criterion, such as an image quality criterion defined by maximal noise amplification in a reconstructed image. The estimated in-plane acceleration factors are used to establish a k-space sampling pattern, which is used to acquire k-space data. An image is reconstructed from the acquired k-space data using a parallel image reconstruction technique.
