Tracking and retrospective correction of high-resolution structural 3D-GRE images is accomplished with a slightly modified EEG cap and sampling system. Carbon wire loops added to the EEG cap allow for motion tracking using gradient-induced signals from native sequence elements, without the need for sequence modification, or electrode-skin contact, while requiring only a short calibration scan, and mounting of the cap. The motion estimates closely resemble estimates from interleaved navigators (mean absolute difference: [0.13,0.33,0.12]mm, [0.28,0.15,0.22]deg). Retrospective correction using carbon wire loops yield similar improvements to Average Edge Strength (12%) for images with instructed movement, and does not degrade images without motion.
