Electrical Impedance Tomography

Next-generation medical imaging techniques

EIT creates real-time conductivity images by measuring surface voltage responses to applied currents - no radiation, portable, and cost-effective medical imaging technology.

Core Principles of EIT

Understanding the fundamental concepts behind electrical impedance tomography imaging

⚡

Current Injection

Safe alternating currents (10-100 kHz) are applied through surface electrodes to create measurable voltage distributions within the tissue.

📊

Voltage Measurement

Surface potential differences are measured at remaining electrodes with high precision to capture conductivity variations.

🧮

Forward Problem

Mathematical modeling predicts voltages for known conductivity distributions using finite element methods and Laplace's equation.

🔄

Inverse Reconstruction

Advanced algorithms reconstruct internal conductivity distributions from boundary voltage measurements through iterative optimization.

Medical Applications

Transforming healthcare with real-time, radiation-free imaging solutions

Electrical Impedance Tomography Device for Body Resistance-Based Imaging

Electrical Impedance Tomography (EIT) devices create images by measuring electrical resistance and capacitance inside the body. They are widely used in hospitals, especially in ICUs, respiratory care, and operating rooms, to monitor lung function in real time without invasive procedures.
