Each oscillator is a silica sphere of 3μm radius, capped on one side with 80nm of carbon and suspended in a water-lutidine mixture held at 28°C.

This open-source project uses 3D printing to build the core of a portable MRI machine, although it still has a lower resolution compared to multi-million-dollar full-sized machines. One tech expert suggested that an AI model be trained on high-field MRI data or the physics of the actual machine to overcome this limitation.
