Are you at risk of heart disease or not? A new touchless device might provide results at a faster rate than the currently used traditional methods. The researchers at the University of Waterloo Canada have developed a novel non-invasive touch less and portable device for improved diagnosis and prevention of various cardiovascular disease. The device can monitor simultaneously the blood flow in the patients at multiple arterial points on the body without direct contact with the skin. It uses a technique called as Coded Hemodynamic Imaging to provide the results. The research study was published in the journal Scientific Reports.
