Ultrasound is a medical imaging technology that utilizes high-frequency sound waves, typically above the range of human hearing, to create real-time images of internal body structures. A transducer emits these sound waves into the body, and the waves reflect back from various tissues and organs. These echoes are received by the transducer and processed by a machine to generate visual representations of the internal landscape. The method is non-invasive and does not employ ionizing radiation, making it valuable for various diagnostic purposes, including visualizing soft tissues, examining blood flow dynamics through the vasculature, and monitoring physiological processes within the body.
