It has been more than 100 years since ultrasound has been used for analyzing materials and echolocation. A bit later, it was adapted for medical diagnostics. Ultrasound became popular and widespread due to the number of benefits. Probably one of the essential features is that it is non-destructive. The other is simplicity and precision. Of course, when we talk about price and simplicity we have X-ray or tomography in mind. Ultrasound can be used in many areas and environments. You can measure geometrical properties of internal structures and physical properties like density and tension. In medicine, ultrasound visualization is mainly used as a non-invasive medical imaging technique using high-frequency sound waves to produce images of internal body structures. It is commonly used to view and diagnose conditions related to pregnancy, the abdomen, and the heart. The images are created by transmitting sound waves into the body, which bounce off internal structures and are detected by a transducer, then processed by a computer to create real-time images. Ultrasound is generally considered safe and painless and does not involve ionizing radiation.
