Keywords: Motion Correction, RF Arrays & Systems
Motivation: To investigate the relationship between head motion and scattering for potential future work on motion correction, using radio frequency sensors to detect changes in head pose.
Goal(s): Establish if scattering changes are linearly related to head translations or rotations.
Approach: Simulations were run using the Sim4Life EM FDTD software with a human model at different positions relative to a coil model.
Results: Translations in the x and y directions varied co-linearly with scattering. However, rotations and z-translation display both linear and non-linear relationships.
Impact: These results allow for a greater understanding of the relationship between head motion and scattering, and demonstrates the potential for scattering to be used as a rapid, contact-free head pose tracker.
