Rotational electrical impedance tomography

A high performance rotational EIT ( REIT) system capable of producing better quality EIT images is developed by expanding the independent measurements. In this system, electrodes are attached to a rotational phantom tank which is driven by a microstepping motor. The measurement site of the electrode pairs can be precisely changed. We increase the independent measurements by moving electrodes from the original location to a subsequent location. Increasing the number of independent measurements enhances the resolution of the impedance image and improves the quality arising from the ill- posed condition. The experimental results clearly show the improvement of the REIT image. It is believed that this improvement will provide help in the field of electrical impedance tomography.
