Abstract
A method for increasing field of view (FOV) in magnetic resonance imaging includes determining linear field gradients of associated with a gradient coil of a magnetic resonance (MR) scanner and using the MR scanner to acquire a k-space dataset representative of a patient using a plurality of readout gradient amplitudes. An extended FOV image is generated based on the k-space dataset using an iterative reconstruction process to solve a forward model that incorporates a measurement of gradient distortion as a deviation from the linear field gradients.
