For medical ultrasound, systems operate at much higher frequencies, typically 1 – 10 MHz. Propagation of ultrasound waves are defined by the theory of acoustics. Ultrasound moves in a wavelike fashion by expansion and compression of the medium through which it travels. Ultrasound waves travel at different speeds depending on material

The critical components of all ultrasound machines include a transducer, a pulser, a beam former, a processor, a display, and a user interface [26, 28]. Transducer, Pulser, and Beam Former. The function of the transducer, which is to emit and receive sound waves, has already been described (see the section "Generation of Sound Waves").

The ultrasound probe, also known as a transducer, is the part of the ultrasound system that touches the patient's body. It holds the crystals that send and receive the sonic pulses. A transducer is defined as a device that transforms energy from one form to another – like a lightbulb or tv antennae.

This first part is about transducers. The transducer, or probe, is one of the - if not the - most important part of your ultrasound machine as it emits and receives the ultrasound waves that travel through the patient's body. The transducer plays a huge role in image quality and is one of the most expensive parts of your ultrasound system, so ...
