O-Space imaging has been shown to provide good reconstructions from a minimal number of echoes, suggesting it could be a useful strategy for accelerated imaging. To further reduce scan time, we are developing strategies that will allow O-space acquisitions to play out in a turbo spin echo train. By carefully ordering the center place acquisitions, using offsets to control the TE of low frequency data, and applying spatially and temporally varying filters in reconstruction, we can dramatically reduce artifacts and improve contrast in TSE O-Space images.
