There are various operating modes of the ultrasound device which are used during ultrasound diagnostics. Basic examination is performed in real-time mode (B – mode). During the performance of heart and blood vessel examination it is hard to manage without the doppler mode – pulsed waves and colors. Ultrasound devices also have other types of operating modes which help to improve basic examinations. Recently it became possible to do the three-dimensional imaging ultrasonography (3D) and three-dimensional imaging in real-time mode (4D).
