Elektrolitzavarokat

Elektrolitzavarokat, often referred to as electrical impedance tomography (EIT), is a non-invasive medical imaging technique that reconstructs the electrical conductivity distribution within an object from measurements of electrical potentials on its boundary. It works by applying small, non-perceptible electrical currents to electrodes placed on the surface of the body. The resulting voltage differences between other electrodes are then measured. Sophisticated algorithms use these voltage measurements to create a cross-sectional image that represents the variations in electrical conductivity. Different tissues and physiological states have distinct electrical properties, which EIT can detect. For instance, air has very low conductivity, while blood and well-perfused tissues have higher conductivity. This property allows EIT to visualize changes in lung ventilation, blood perfusion, and brain activity. EIT is particularly promising for bedside monitoring due to its low cost, portability, and ability to provide continuous imaging without ionizing radiation. Applications are being explored in areas such as pulmonary monitoring in intensive care units, stroke detection, and functional brain imaging. While still an evolving technology, EIT offers a unique and complementary imaging modality to established techniques like X-ray and MRI.
