Introduction
The Impedance Imaging Research Center (IIRC) was founded in July, 2002 as an Engineering Research Center (ERC) supported by the Ministry of Science and Technology (MOST), Korea Science and Engineering Foundation (KOSEF), and Kyung Hee University (KHU). With its main office and laboratories located at KHU, more than 17 faculty members from 6 different universities in Korea and numerous researchers have joined the center. Since the nature of impedance imaging research is interdisciplinary, specialties of the members include biomedical engineering (especially, medical imaging and instrumentation), electrical engineering, mathematics, numerical analysis, and biomedical sciences.
