Hyperband Transition

by on September 14, 2020 10:57 am
Executive Summary The GE product Hyperband BOLD and diffusion sequences are a result of close collaboration between GE scientists and engineers with the CNI staff.  The CNI SMS implementation, which we called the “MUX” research sequence, served as a resource and a benchmark for the GE Hyperband product.  Over the last several months Adam and… Read more Hyperband Transition

Upgrade Plan for DV26

by on August 28, 2017 9:18 am
Executive summary We will be upgrading the GE software and computational infrastructure in late September (from DV25 to DV26). The reasons and implications for your projects are explained below in detail. To migrate the CNI sequences to this new environment, the CNI development team needs time on the scanner (we estimate about 12 hours).  As… Read more Upgrade Plan for DV26

Updates for multiband reconstruction

by on March 15, 2017 10:31 am
The CNI has recently introduced a new option for reconstructing SMS (aka, multiband or mux) scans. The default reconstruction method in the SMS reconstruction pipeline is currently 1D-GRAPPA (Blaimer M. et al. MRM 2013). Based on recent research and testing, we believe that the split-slice-GRAPPA (Cauley SF, et al. MRM 2014) reconstruction algorithm does a better… Read more Updates for multiband reconstruction
