Ultrasound waves are sound waves that are too high in frequency to be within human hearing range. They are used in medical imaging, notable in ultrasonic scanning, enabling a computerized image of the area scanned to be generated based on the quantity and nature of ultrasound waves that are reflected back by different tissues. In other uses, these waves can eradicate unwanted substances or tissue growths. They are also employed in physiotherapy methods, where the physiotherapist uses a generator that targets the patient with high frequency waves causing heat, thus reducing pain, improving circulation, or freeing up stiff joints.
