Improvements in Electrical Impedance Tomography (EIT) are discussed: first, the extension of our current real-time EIT system to allow for multiple shapes by post-hoc estimation of the image, then the prospect of taking images of a static material, but with the homogeneous and inhomogeneous data taken at two different frequencies. Images with various shapes are produced and shown; the impracticality of using multiple frequency imaging with the current EIT system is also shown. Multiple frequency images are produced with a different, non-real-time system. In addition, the procedure for producing the phantom test material is discussed.


Credit goes to Yi Zheng for proposing using frequency dispersion for EIT imaging, to Gegg for making the cross-frequency EIT image in chapter 8, and to Monali for designing the base software used for our EIT images.
