Abstract
A system and method for combining k-space data acquired on multiple different receiver channels in a multichannel receiver is provided. One or more convolution kernels are used to combine the k-space data. Each convolution kernel is designed as the combination of one or more channel combination kernels and an alias-suppressing kernel. The channel combination kernels are designed to have a smaller sample spacing than the acquired data, and the alias-suppressing kernel is designed to suppress aliasing artifacts in stopbands defined by the sample spacing of the channel combination kernels.
