Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation, uses specific wavelengths of red and near-infrared light to penetrate the skin and stimulate cellular ...
Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions.
Credit: Caltech Engineers in California have devised a headset that uses lasers to assess the wearer's risk of having a stroke in real time. Although the headset's many sensors and wires make it both ...
