Ceramic motors will allow surgeons to operate in MRI scanners

An international team of engineers and researchers has developed a surgical robot that incorporates non-magnetic ceramic motors that allow it to be used safely in the strong magnetic field of an MRI (magnetic resonance imaging) system. The neuroArm robot will allow surgeons to perform precision surgery on patients while they are in an MRI scanner, which can be used to view the progress of the operation in real time.

Until now, the magnetic nature of conventional electric motors and their use of metal components has prevented surgeons from conducting operations within MRI machines. The new arm, which is formed from plastics, titanium and other non-magnetic materials, can be used safely in scanners to perform intricate surgery to accuracies of 0.01mm.
