Doctors may have a new weapon when it comes to the early detection of heart problems.
Scientists at a Canadian university have developed a portable, noninvasive, touchless device that can fully image a person's body and monitor the blood flow throughout, according to the International Business Times.
Developed at the University of Waterloo in Ontario, Coded Hemodynamic Imaging uses photoplethysmography and can "monitor a patient's blood flow at multiple arterial points simultaneously without making direct contact with the skin," according to the report.
Previously, photoplethysmography only worked when it was close to the body.
According to the article, however, "the new device has sensors that are able to detect hemodynamic waveforms from a distance."
