Wait, Commonwealth Fusion Systems is already building 20T REBCO magnets, can't those meet the requirements for MRIs?

- cthalupa 3y agoYou're right - for whatever reason I had convinced myself YBCO had issues with both high current and high field. It's just high current - anything outside of a single grain has low current density. Doing some more research to help make up for my spreading of incorrect info, I did stumble across this - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5472374/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5472374/ - it seems like it's a variety of factors that make most HST not really commercially viable for MRI machines at current. Mitsubishi has even made a small scale MRI machine with HTS - https://www.medicaldesignandoutsourcing.com/worlds-first-3-tesla-mri-with-high-temperature-coils/ https://www.medicaldesignandoutsourcing.com/worlds-first-3-t... - though I can't find any newer details around it, despite the timeline provided in the article.
- ralfd 3y agoPhilips has this press release about researching high temperature MRI from 2022: https://www.usa.philips.com/a-w/about/news/archive/standard/news/press/2022/20221130-philips-signs-research-agreement-to-explore-new-magnet-technologies.html https://www.usa.philips.com/a-w/about/news/archive/standard/... I guess the need is somewhat alleviated by using MRI which seal their helium: https://www.usa.philips.com/healthcare/resources/landing/the-next-mr-wave/sealed-mr-technology https://www.usa.philips.com/healthcare/resources/landing/the...
