Bio imaging is a technique based on multiple measurements of impedance. When it is used for medical application it relates the biophysical properties of tissues and blood to produce a reconstructed image or map that represent the human physiology. It relies of the bio impedance properties of the biological medium, for example in tumours the cell density often increases. Bio imaging which is often called Electrical impedance tomography (EIT) is a relatively new imaging method that has evolved over the past 30 years. It has the potential to be of great value in clinical diagnosis; however, it is a technically difficult problem to solve in terms of developing hardware for data capture and the algorithms to reconstruct the images. The development of EIT and how it has evolved are presented specifically addressing its clinical applications, examining hardware for the collection of data and reconstruction algorithms to generate images. Finally, this review looks at future developments that are evolving from EIT. These new variations use mixed modalities that may produce interesting new clinical imaging tools.
