How does ultrasound technology works?

1st Glimpse Inc. 3D/4D Ultrasound - Brooklyn, NYC

An ultrasound is a series of an extremely high frequency of sound waves. Since these sound waves belong to a frequency that is unable to be heard by the human ear, they cannot be sensed by the patient or her fetus. An instrument referred to as a transducer, which resembles a stethoscope, is positioned on the abdomen of the woman. As high-frequency sounds traverse her skin and rebound off anything they contact within the abdomen, an image that looks like a blurry black and white picture is generated.
