In this work, a new implementation of the HighlY constrained Cartesian Reconstruction (HYCR) is proposed to address the memory and computation time challenges of the original HYCR implementation. This was achieved by performing the channel combination in k-space before Fourier Transform using the Direct Virtual Coil (DVC) technology. Comparison of overall image quality, line profiles and temporal waveform was performed for the original and the proposed HYCR implementations, using a pulmonary perfusion application as an example.
