Abstract
A method and system for image reconstruction are provided. A k-space including a first part and a second part may be set. The first part of the k-space may be filled with a matrix including data. The matrix may be filtered to produce a filtered data matrix. The second part of the k-space may be padded. Iterations of an objective function for a target array of data in image domain may be performed based on a constraint. The objective function may be based on a total variation of the target array of data and a function relating to the Fourier transform of the target array of data, the filtered data matrix in the first part, and the padded data in the second part of the k-space. An image may be reconstructed based on the target array of data.
