Vein visualisation complex developed by Grodno scientists
A hardware and software complex for vein visualisation has been developed by scientists of the Yanka Kupala Grodno State University, sb.by reports with reference to the educational institution
The system based on near-infrared machine vision technologies is designed to facilitate the search for veins during medical procedures such as blood collection and injections. Associate Professor, Candidate of Physico-Mathematical Sciences Andrei German, who heads the Department of Electrical Engineering and Electronics, joined a graduate in the Industrial Robots and Robotic Complexes specialty to develop the complex.
"The complex uses safe near-infrared light with a wavelength of 850nm, which is directed at the patient's skin," the scientists explained. “Haemoglobin in the blood absorbs infrared radiation, while the surrounding tissues reflect it. The resulting image is processed on a personal computer using specialised mathematical algorithms. The contrast is enhanced and the blood vessels are seen well in real time.”
According to the institution, the use of the complex will reduce the number of unsuccessful vein punctions, which will lead to a reduction in the cost of consumables, save working time, cut the expenses on training medical personnel, improve the quality of medical services, and increase patient comfort.
As reported, the complex is easy to use, and it boasts an affordable price, portability and safety, as it does not require invasive methods and dangerous radiation.
“Among the potential consumers of the development are expected to be healthcare institutions, as well as students of technical specialties, who can use the complex as a demonstration laboratory model for studying machine vision technologies and image processing algorithms," the educational institution concluded.
