Researchers propose new contactless method for measuring blood flow in the upper limbs

The research team from Russia proposed a new contactless method for measuring blood flow in the upper limbs. The method is based on video recording of the skin surface under green light measuring the absorption of red blood cells. This helps to see how effective the circulatory system and the blood flow regulation are.
