a, Front-view of the gradient coils assembly mounted on a toilet seat for continuous GI monitoring. b, Side-view of the toilet seat with the gradient coils. Two iMAG devices are placed in a tank filled with saline solution to demonstrate 3D localization. The experiment is repeated for n = 20 different locations of the iMAG devices in the FOV. c, Error obtained at all the locations is clustered together and plotted. d, Error at each location is plotted separately. Error reported as mean ± s.d.: 1.09 ± 1.29 mm (X), 1.25 ± 1.22 mm (Y), 0.95 ± 1.05 mm (Z). This prototype shows the ability of our technology to be deployed in common human-specific settings.
