Quantitative imaging with electrical impedance spectroscopy
Physics in Medicine and Biology, 2012Electrical impedance spectroscopy (EIS) is a noninvasive modality that can be used to determine the electrical admittivity inside a body given a discrete set of current/voltage measurements made on the surface. Of particular interest is the use of EIS in the diagnosis of breast cancer, as the admittivity spectra of malignant and benign tumors differ ...

Electrical Impedance Spectroscopy in Skin Cancer Diagnosis
Dermatologic Clinics, 2017Electrical impedance spectroscopy (EIS) is a noninvasive method that aims to help diagnose skin cancer. The EIS device consists of a handheld probe with a disposable electrode that is applied directly on the skin and uses electrical impendence differences to differentiate between normal and abnormal skin lesions.

Electrical impedance spectroscopy and diagnosis of tendinitis
Physiological Measurement, 2009There have been a number of studies that investigate the usefulness of bioelectric signals in diagnoses and treatment in the medical field. Tendinitis is a musculoskeletal disorder with a very high rate of occurrence. This study attempts to examine whether electrical impedance spectroscopy (EIS) can detect pathological changes in a tendon and find the ...

Electric impedance spectroscopy of human atherosclerotic lesions
Atherosclerosis, 2009The 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 ...

Code-Division-Multiplexed Electrical Impedance Tomography Spectroscopy
IEEE Transactions on Biomedical Circuits and Systems, 2009Electrical 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 and Roots
2011This 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

Electrical Impedance Spectroscopy of the Human Prostate
IEEE Transactions on Biomedical Engineering, 2007Tissue electrical impedance is a function of its architecture and has been used to differentiate normal and cancer tissues in a variety of organs including breast, cervix, skin, and bladder. This paper investigates the possibility of differentiating normal and malignant prostate tissue using bioimpedance spectra.

Parametric modelling for electrical impedance spectroscopy system
Medical & Biological Engineering & Computing, 1996Three 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
2018This 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.
