k-Space channel combination for multi-channel acquisitions promises to reduce reconstruction latency by combining data across channels during data acquisition and reducing the number of Fourier transforms required for data reconstruction. In this work, a method is proposed that enables k-space channel combination for non-Cartesian acquisitions. The proposed approach combines Direct Virtual Coil (DVC) channel combination calibration with conventional convolution gridding. Image quality is evaluated using radial and spiral data sets.
