An improved method of k-space channel combination for non-Cartesian acquisitions is described. With the proposed method, it is possible to simultaneously grid and perform channel combination in k-space using small width (4x4) convolution kernels for 2D non-Cartesian imaging. Enabling good image quality with small convolution kernels could lead to very fast non-Cartesian multi-channel image reconstruction.
