Approximation of full-boundary data from partial-boundary electrode measurements [PDF]

, 2017
Measurements on a subset of the boundary are common in electrical impedance tomography, especially any electrode model can be interpreted as a partial boundary problem. The information obtained is different to full-boundary measurements as modeled by the

Dynamic Hand Gesture Recognition Using Electrical Impedance Tomography

Sensors, 2022
Electrical impedance tomography (EIT) has been applied in the field of human-computer interaction due to its advantages including the fact that it is non-invasive and has both low power consumption and a low cost.

Electrical Impedance Tomography

British Journal of Radiology, 1997
Electrical impedance tomography (EIT) is a technique which allows cross-sectional images related to the local electrical impedance within an object to be reconstructed from sets of measurements made on its surface. The main drive behind the development of EIT has been its possible application in medical imaging, as biological tissues are known to ...

Exploratory Study on the Methodology of Fast Imaging of Unilateral Stroke Lesions by Electrical Impedance Asymmetry in Human Heads

The Scientific World Journal, 2014
Stroke has a high mortality and disability rate and should be rapidly diagnosed to improve prognosis. Diagnosing stroke is not a problem for hospitals with CT, MRI, and other imaging devices but is difficult for community hospitals without these devices.

Computing Volume Bounds of Inclusions by EIT Measurements

, 2007
The size estimates approach for Electrical Impedance Tomography (EIT) allows for estimating the size (area or volume) of an unknown inclusion in an electrical conductor by means of one pair of boundary measurements of voltage and current.

Expectation Propagation for Nonlinear Inverse Problems -- with an Application to Electrical Impedance Tomography [PDF]

, 2013
In this paper, we study a fast approximate inference method based on expectation propagation for exploring the posterior probability distribution arising from the Bayesian formulation of nonlinear inverse problems. It is capable of efficiently delivering

Therapeutic effects of low-intensity transcranial focused ultrasound stimulation on ischemic stroke in rats: An in vivo evaluation using electrical impedance tomography

Neural Regeneration Research
Although previous studies have demonstrated that transcranial focused ultrasound stimulation protects the ischemic brain, clear criteria for the stimulation time window and intensity are lacking.
