Revolutionary approach to lung diagnostics: energy-saving LETS system changes the face of modern medicine
In response to the growing needs of modern medicine, a team of scientists has developed a modern lung imaging system that combines high diagnostic precision with exceptional energy efficiency. Lung Electrical Tomography System (LETS) is an innovative solution in the field of electrical impedance tomography (EIT), which significantly expands the possibilities of non-invasive diagnostics of respiratory diseases. This system is distinguished not only by advanced measurement technology, but also by the ability to monitor patients long-term with minimal energy consumption.

The heart of the LETS system is a vest equipped with 102 textile electrodes, precisely placed to record changes in electrical impedance within the lungs. These measurements, analyzed by advanced reconstruction algorithms and machine learning systems, enable the identification of pathologies with high accuracy. The LightGBM model used achieved a disease classification efficiency of 91.8%, which places this technology at the forefront of modern diagnostic methods. The recognized disease entities include, among others, chronic obstructive pulmonary disease, acute respiratory distress syndrome, pneumothorax, pneumonia, bronchospasm and pulmonary hypertension.
An important aspect of the LETS system is its energy efficiency. Thanks to the use of modern DC/DC converters and optimized electronic architecture, the device operates without the need for intensive cooling, which makes it an excellent solution for long-term clinical and home applications. The research team also proved that for effective diagnostics it is enough to activate only selected electrodes, which additionally reduces energy demand and increases the durability of the system.
In the face of the limitations of traditional imaging methods, such as computed tomography or chest radiography – which require expensive infrastructure and are associated with exposure to radiation – the LETS system presents itself as a safe, mobile and accessible alternative. Thanks to the ability to obtain results in real time and the lack of ionizing radiation, this technology ideally fits the needs of modern healthcare, especially in the context of patients with chronic diseases requiring continuous monitoring.
The LETS system is an example of a balanced approach to medical technology – combining high diagnostic quality, energy efficiency and the potential for integration with telemedicine platforms. Work is underway to implement the solution in the clinical environment and to expand its applications to other areas of medicine. In the future, full remote monitoring of patients’ condition will be possible, which can significantly relieve healthcare systems and increase the availability of specialist diagnostics.
