The most powerful CT Scan has been unveil very recently, with a magnet able to pull almost 12 teslas (where regular ones usually go to 1,5 to 3 teslas)[1]. Source is in french, but you'll find a similar video of... a pumpkin :) They explain in the article that pumpkins are used because they share a similar shape and structure as well as water ratio as a human head. They got the magnet from previous research efforts from a research team dedicated to that domain (part of the french research around nuclear and alternative energies). Instead of trashing the 130t magnet, they proposed to adapt it for medical imagery. It will know help research on the Alzheimer disease. https://www.francetvinfo.fr/sante/decouverte-scientifique/sciences-l-irm-le-plus-puissant-au-monde-vient-de-livrer-ses-premieres-images_4797467.html https://www.francetvinfo.fr/sante/decouverte-scientifique/sc...

That's MRT - magnetic resonance imaging. CT scans - computed tomography - use x-rays. https://en.wikipedia.org/wiki/CT_scan https://en.wikipedia.org/wiki/CT_scan https://en.wikipedia.org/wiki/Magnetic_resonance_imaging https://en.wikipedia.org/wiki/Magnetic_resonance_imaging The applications for both are slightly different. https://www.medicalnewstoday.com/articles/154877#possible_risks https://www.medicalnewstoday.com/articles/154877#possible_ri... There is a nice course on edX (the content is free), "Introduction to Biomedical Imaging", which teaches the basics of the most common imaging technologies (also adds ultra-sounds and radiology-based scans): https://www.edx.org/course/introduction-to-biomedical-imaging https://www.edx.org/course/introduction-to-biomedical-imagin...
