Design of electrical impedance tomography for biomedicine

Abstract

Electrical Impedance Tomography (EIT) has an advantage than another imaging systems in the medical field, they are safe, fast, and simple. The role of EIT is promising, so that it is necessary to develop electrical impedance tomography devices, especially in the biomedical field. we have successfully constructed a multi-frequency EIT system for biomedicine consisting of an oscillator, buffer, VCCS (voltage controlled current source), mux-demux, differential amplifiers based on Arduino Mega. The system succesfully has been tested to produce an image of conductors, insulators, and animal organs so that suitable for biomedical field.
