Short summary
The construction, operation and analysis of a spectral electrical impedance tomography (sEIT) field monitoring setup with high spatial and temporal resolution are presented. Electromagnetic induction errors are corrected, allowing the recovery of images of in-phase conductivity and electrical polarisation of up to 1 kHz.
