Magnetic Resonance Imaging‐Based Tracking and Navigation of Submillimeter‐Scale Wireless Magnetic Robots

Advanced Intelligent Systems, 2021
Magnetic resonance imaging (MRI) scanners have recently been used for magnetic actuation of robots for minimally invasive medical operations. Due to MRI's high soft‐tissue selectivity, it is possible to obtain 3D images of hard‐to‐reach cavities in the human body, where the wireless miniature magnetic robots powered by MRI could be employed for high ...
