Ultrasound is a diagnostic test using high-powered sound waves through a probe to the tissue or organ to be examined and reflects to create an image, which can examine various organs, show abnormalities, and can help doctors diagnose diseases. The resulting images can be 2D images that move continuously according to the movement of the probe at that time, or can be used to create 3D and 4D images like taking a photograph, such as examining a fetus. In addition to being harmless, ultrasound examinations can also be performed without the patient feeling pain in the area being examined, apart from slight pressure.

There is also technology to detect liver fibrosis and measure the amount of fat accumulated in the liver for patients at risk, all at once quickly and precisely, to diagnose and plan treatment, so that patients will not experience any pain or complications during and after the examination.
