BREAST IMAGING USING 3D ELECTRICAL IMPEDENCE TOMOGRAPHY

Breast imaging using 3D electrical impedence tomography.

AIM To determine the diagnostic efficiency of 3D Eletrical Impedance Tomography (EIT) compared to Mammography (MG) and Ultrasonography (USG) in imaging the breast. MATERIALS AND METHODS A group of 88 patients presenting with various breast complaints was examined using combined Mammography and Ultrasonography (MG & USG) or either of these modalities alone. The same patients were then examined...

Breast Imaging using Electrical Impedance Tomography (EIT)

Imaging UXO Using Electrical Impedance Tomography

This paper reports the results of tests where electrical impedance tomography (EIT) was evaluated as a tool for detecting and locating buried unexploded ordnance (UXO). The method relies on the electrolytic polarization induced at the boundary between soil and buried metal. This induced polarization (IP) produces a measurable phase delay between the electric current imposed on the subsurface an...

Breast imaging using electrical impedance tomography: correlation of quantitative assessment with visual interpretation.

BACKGROUND Electrical impedance tomography (EIT) is a new non-invasive, mobile screening method which does not use ionizing radiation to the human breast; allows conducting quantitative assessment of the images besides the visual interpretation. The aim of this study was to correlate the quantitative assessment and visual interpretation of breast electrical impedance tomographs and associated f...

Breast Cancer Detection Using Electrical Impedance Tomography: Spice Simulation

A WO dimensional. 16-electrode Electrical Impedance Tomography (EIT) system has been simulated using PSPICE to determine whether EIT can be used as a screening technique for early breast cancer detection. Simulation results show that a tumor of area of 1% of the cross-sectional breast model area produces more than 4% variation in the voltage magnitude at the surface electrodes when compared to ...
