NIMS Transition to Flywheel: Part One

BACKGROUND When planning the CNI we committed to providing the community with data management services. As many of you know, most MRI centers do little more than hand the user a DVD at the end of the session, and wish them well. CNI users are supported much more extensively. Data acquired on our scanner are read more…

CNI scanner upgrade to DV26

After weeks of testing, the CNI will upgrade the scanner’s software to DV26 on Monday, Nov 12, 2017. All existing protocols will be migrated to the new platform, and we fully expect they will perform as they do on the current platform. Data will continue to be stored in NIMS as they are now as read more…

Upgrade Plan for DV26

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…

Choosing an MRI protocol for your experiment

The CNI’s Wiki pages offer general advice about how to set up your scan protocols and save the information for later use. The wiki pages take you through the template protocols we think are most widely used. These protocols can be found on the the scanner console, saved under “CNI/head” within the protocol pool. The read more…

Optimizing image quality: Fieldmaps and shimming

Acquiring a high quality fieldmap of the mean magnetic field is crucial to obtaining a good measurement.  Making sure you set the parameters so that this field map is obtained as part of your protocol is something we help you with.  There are cases, including new sequences, where this can require some extra attention. The read more…

Updates for multiband reconstruction

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…
