👉 Metrotometry is a type of measurement technique used in medical imaging to measure the speed and direction of blood flow. It involves using high-speed cameras to capture images of an artery or vein, which are then analyzed using mathematical algorithms to determine the velocity and direction of blood flow. This method can be used for various purposes such as diagnosing heart disease, evaluating stroke risk, and monitoring blood pressure changes in patients with chronic obstructive pulmonary disease (COPD).
