Ultrasound technology is the application of high frequency sound waves to produce diagnostic images. These images can be used in both a diagnostic and therapeutic manner.
Ultrasound technology is a safe and painless way to see the different tissues of the Healthy Body. A small device like a microphone called a transducer, sends and receives sound waves that are stored in the machine. The sound waves are analyzed and recorded as a graphic image.
Doppler studies use the same ultrasound application to display motion in an audio (continuous wave Doppler), visual (colour Doppler) or graphical (pulsed wave Doppler) form. This is useful in the study of arteries and veins to detect blood flow.
