Classification of breast tissue by electrical impedance spectroscopy

Medical & Biological Engineering & Computing, 2000
Electrical impedance spectroscopy is a minimally invasive technique that has clear advantages for living tissue characterisation owing to its low cost and ease of use. The present paper describes how this technique can be applied to breast tissue classification and breast cancer detection.

Electric impedance spectroscopy of human atherosclerotic lesions

Atherosclerosis, 2009
The aim of this in vitro study was to investigate the feasibility of a new highly flexible microelectrode on human tissue and its potential of differentiating atherosclerotic lesions by electric impedance spectroscopy (EIS).Electric impedance measurements (EIM) were performed on 148 spots of 7 aortic and 6 femoral human arteries at 1kHz, 10kHz and ...

Electrical Impedance Spectroscopy and Roots

2011
This chapter reviews studies dealing with the characterization of the plant root system by the electrical impedance method, i.e., with resistance and capacitance at a single frequency or at multifrequencies, according to the approach used in electrical impedance spectroscopy (EIS). Several studies have shown a correlation between electrical capacitance

Parametric modelling for electrical impedance spectroscopy system

Medical & Biological Engineering & Computing, 1996
Three parametric modelling approaches based on the Cole-Cole model are introduced. Comparison between modelling only the real part and modelling both the real and imaginary parts is carried out by simulations, in which random and systematic noise are considered, respectively.

Electrical impedance spectroscopy and the diagnosis of bladder pathology

Physiological Measurement, 2006
Bladder pathology is usually investigated visually by cystoscopy. At present, definitive diagnosis of the bladder can be made by biopsy only, usually under general anaesthesia. This is a relatively high-cost procedure in terms of both time and money and is associated with discomfort for the patient and morbidity.

Electrical Impedance Spectroscopy

2018
This chapter gives some background on impedance spectroscopy and tissue impedance but also about the instrumentation used for measuring transfer impedance of a biological material under study. The instrumentation concerned here is the current source for applying a current to tissue and the differential amplifier for measuring the resultant voltage.

Code-Division-Multiplexed Electrical Impedance Tomography Spectroscopy

IEEE Transactions on Biomedical Circuits and Systems, 2009
Electrical impedance tomography uses multiple impedance measurements to image the internal conductivity of an object, such as the human body. Code-division multiplexing is proposed as a new method that can provide simultaneous impedance measurements of the multiple channels.

Electrical Impedance Spectroscopy in Plant Biology

2021
Electrical impedance spectroscopy (EIS) is a non-invasive approach to characterize the electrical properties such as resistance and capacitance of many materials including biological tissues. For measurement, the plasma membrane acts as an electrical insulator that controls the movement of ions and electrolytes across the cells.

Electrical Impedance Spectroscopy of Prostatic Tissues

2007
Prostate cancer has a high rate of incidence in the United State with over 27,000 deaths attributed to the disease in 2006. The current screening methods of digital rectal examination (DRE) and prostatic specific antigen (PSA) monitoring are extremely sensitive to physiological changes in the prostate, however their specificity is limited leading to ...
