Conclusion
The design details of a simple and low-cost electrical impedance tomography system are made available for public access.
Supporting Evidence
- The system was tested under both static and dynamic modes, showing better results in dynamic mode due to error cancellation.
- The design is aimed at being low-cost and efficient for both medical and industrial applications.
- The system's performance was validated through simulations and real measurements.
Takeaway
This study presents a simple and affordable way to create a system that can take images of electrical properties in materials, which can be useful in medical and industrial applications.
Methodology
The system consists of a PC with an I/O card, current generator, multiplexer, power supply, and electrodes, using MATLAB for image reconstruction.
Limitations
The system has limitations in image resolution and is sensitive to noise and electrode positioning errors.
