An ultrasound scanner is a device that uses ultrasonic waves to create images of the human body's internal organs. A doctor may take images of the patient's organs such as the liver, gallbladder, uterus, kidneys, and so on. It aids the doctor in detecting abnormalities such as gallbladder and kidney stones, as well as tumours in various organs. In this technique, ultrasonic waves travel through the body's tissues and are reflected from a region with a change in tissue density.
