The Hardware
Our SIGNA™ Premier is GE Healthcare’s newest ultra-premium 3.0T MR system that combines powerful SuperG gradient technology and a 146-channel Total Digital Imaging (TDI) RF chain into a true 70 cm wide bore. GE has delivered the newest version of their console computer with an upgraded version of console software, as well as two image processing computers which will improve our ability for real time and post-scan processing of anatomic, functional, spectroscopic, and diffusion tensor imaging data.
We are currently utilizing a 48-channel head array provided by GE for use with the Signa Premier system. For physical specifications of the GE 48-Channel Coil, click here.
We have conducted comparative SNR measurements between the two coils using the ABCD sequences as a baseline. Please click here for the results.

Designing a Study'
Please download this checklist of steps to complete before scanning .
Here is a summary of the steps:
- Complete the MRI Approval For Grant Application in REDCap
- Submit MRI grant application to business office
- Obtain MRI Director Protocol Approval and submit to the relevant IRB
- After approval, complete the Project Initiation Form in REDCap
- Ensure all staff have undergone safety training
- Contact MRI Administrator to begin scheduling scans
The MRI Research program actively supports a number of pulse sequences and scan protocols with pre-defined parameters, all of which include sequences necessary to use standardized processing pipelines, including all recommended structural, functional, and scouting & measuring sequences for distortion correction, etc.
If you wish to use sequences not included in these protocols, including newer modalities / sequence types, as well as sequences specific to multi-site projects, industry studies, etc., we're happy to accommodate these, but we ask that you please discuss your protocol and sequence parameters with Feng Liu and Gaurav Patel to ensure full compatibility with our scanner platform as well as optimal data quality.
