Impedance Tomography

Electrical impedance The EIT uses a series of electrodes spread across the chest to generate cross-sectional images of the internal distribution of electrical impedance. The electrodes send and receive electrical impulses, and the image of the thorax shows the areas that change in volume most dramatically. Electrical impedance in thoracic images is high in areas that are well-ventilated, and low in regions that do not have a significant change in volume. The system is composed of many components, including electrode array, data acquisition, and image reconstruction. In addition, a digital controller is used to process the images. The electrodes and…
