Ultrasonic diagnosis of water in lungs

Posted by STEP RI d.o.o.Responsive · Knowhow and Research output · Croatia

Summary of the technology

Pulmonary edema is a condition caused by excess fluid in the lungs. Usage in the diagnosis of lung disease due to the specific organ structure is limited comparing to the examination of other organs. With this technology, beside the possibility to use it as a non-invasive diagnostic tool for lungs it also offers opportunity to monitor the effectiveness of medical treatment and to adjust right cure and dose for further treatment of lungs and/or heart.

New and innovative aspects

Pulmonary edema is a condition caused by excess fluid in the lungs. B-lines appear on the monitor of the ultrasound device as vertical lines flashing on the screen whose intensity and number vary. Due to this variability and the slow movement of the human eye, it is difficult to calculate the number of B-lines precisely, even in experienced physician. This software solution, that can be embedded in ultrasound machine, detects and shows exact number of B-lines in defined time frame on the screen and helps physician in more objective examination of patient.

Main advantages of its use

The main idea of invention is to make more objective the examination and to back up physicians (especially less experienced stuff and to reduce necessity of engaging more experienced stuff if it can be avoided which can improve organization within hospitals) Objective determination of B-lines which brings Ultrasound machines more useful in field of diagnosis of lungs condition. Non invasive approach in monitoring treatment of patients with option to track improvement of patient condition after taking therapy.


In most cases, heart problems cause pulmonary edema. But fluid can accumulate for other reasons, including pneumonia, exposure to certain toxins and medications.
