Ultrasound diagnostics is a method of studying the size, structure, shape, position, and movement of organs and tissues using ultrasound in real time. The method is based on the ability of ultrasonic waves to pass through various tissues of the body, reflecting differently from structures of different densities. These reflections are recorded by a sensitive sensor and, with the help of special software, are converted into an image on the monitor of the ultrasound scanner. There are various types of ultrasound diagnostics. The most commonly used are scanning (what is traditionally understood as the concept of ultrasound) and dopplerography (a type of ultrasound diagnostics that allows you to study the speed, direction and other characteristics of blood flow).
