As the sound waves bounce off internal organs, fluids and tissues, the sensitive receiver in the transducer records tiny changes in the sound's pitch and direction.
These signature waves are instantly measured and displayed by a computer, which in turn creates a real-time picture on the monitor.
In an ultrasound exam, a transducer both sends the sound waves and records the echoing waves.
When the transducer is pressed against the skin, it sends small pulses of inaudible, high-frequency sound waves into the body.
You should wear a loose-fitting, two-piece outfit for the examination.
Ultrasound exams do not use radiation (as used in x-rays).
It allows the doctor to see and evaluate blood flow through arteries and veins in the body.
During an obstetrical ultrasound the examiner may evaluate blood flow in the umbilical cord or may, in some cases, assess blood flow in the fetus or placenta.
One or more frames of the moving pictures are typically captured as still images. The movement of the embryo or fetus and his or her heartbeat can be seen as an ongoing ultrasound movie.
Ultrasound devices also use Doppler, a special application of ultrasound, which processes echoes produced by blood flowing through the fetal heart, blood vessels and umbilical cord and turns them into audible sound.
The technologist applies a small amount of gel to the area under examination and places the transducer there.
