Applications of Electrical Impedance Tomography in Neurology
Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...
متن کاملFrequency-Division Multiplexing for Electrical Impedance Tomography in Biomedical Applications
Electrical impedance tomography (EIT) produces an image of the electrical impedance distribution of tissues in the body, using electrodes that are placed on the periphery of the imaged area. These electrodes inject currents and measure voltages and from these data, the impedance can be computed. Traditional EIT systems usually inject current patterns in a serial manner which means that the impe...
متن کاملAppendix B Introduction to biomedical electrical impedance tomography
One of the attractions but also difficulties of biomedical EIT is that it is interdisciplinary. Topics which are second nature to one discipline may be incomprehensible to those with other backgrounds. Not all readers will be able to follow all the chapters in this book, but I hope that the majority will be comprehensible to most, especially those with a medical physics or bioengineering backgr...
متن کاملMonotonicity-based Electrical Impedance Tomography Lung Imaging
This paper presents a monotonicity-based spatiotemporal conductivity imaging method for continuous regional lung monitoring using electrical impedance tomography(EIT). The EIT data (i.e., the boundary current-voltage data) can be decomposed into pulmonary, cardiac and other parts using their different periodic natures. The time-differential current-voltage operator corresponding to lung ventila...
متن کاملActive Electrode Based Electrical Impedance Tomography System
Abstract: EIT can image the distribution of ventilated lung tissue, and is thus a promising technology to help monitor patient breathing to help selection of mechanical ventilation parameters. Two key di culties in EIT instrumentation make such monitoring di cult: 1) EIT data quality depends on good electrode contact and is sensitive to changes in contact quality, and 2) EIT electrodes are di c...
