There are several properties of ultrasound that are useful in clinical cardiology. Since ultrasound is a mechanical wave in a longitudinal direction, it is transmitted in a straight line and it can be focused. These waves obey laws of reflection and refraction. Since small objects in the human body will reflect ultrasound, it is possible to collect the reflected data and compose a picture of these objects to further characterize them. | There are several properties of ultrasound that are useful in clinical cardiology.
