Neuroimaging Facility Updates and Advances

I've updated the scripts for graphing our stability metrics using R rather than Matlab (thanks, ChatGPT!). Let me know what you think. One note, the change in scanning protocol to ensure the phantom was really in isocenter for the 64-channel coil tests is really...

We're very excited to introduce newly-designed MR-compatible cable clips for the Cima.X scanner. These clips are meant to be used with peripheral equipment such as button boxes, headphones, or squeeze-balls to keep the cables from getting caught when the MRI scanner...

Summary I've updated my stability scan summary code to bring all the measures into a single plot. Hopefully it's not too busy. Details on stability scans below. My last post explained the bimodal distribution of the "Mean ghost" measure for the 64-channel coil....

Summary Weekly MRI quality assurance (QA) scans are performed with the 64-, 32-, and 20-channel head coils. Scan sequences are based on recommendations of Pyles et al. (see https://sites.google.com/view/mri-facility-qa) and stability measures are calculated using the...

We have implemented a weekly quality assurance (QA) protocol in which we assess the stability of the fMRI signal from the Cima.X scanner using the 64-, 32-, and 20-channel head coils and both standard Siemens and CMRR multi-band EPI pulse sequences. The scan protocol...
