What a milestone! The first open-source MRI scanner, the OSI² ONE, has been built and delivers exciting first in-vivo MR images. OSI² ONE was anounced in 2022 at the ISMRM workshop on low-field MRI and a first prototype travelled to the ISMRM 2022 in London for a live presentation. At the moment three copies have been successfully built in the Netherlands, Uganda and Germany and more replicas are following.
