What is Ultrasound? 
Ultrasound is an imaging technique that uses high-frequency sound waves, generated by a handheld device called a transducer. The transducer is placed on the skin where it uses the echoes created by the sound waves to create images of the internal organs. Ultrasound does not involve radiation, which is one of the reasons that it is routinely used to examine fetuses in utero. There are many other applications for ultrasound, such as evaluating abdominal and pelvic organs, assessing blood vessels for clots or atherosclerotic plaque, examining the superficial structures of the neck and extremities, and providing guidance for biopsies or for draining fluid collections.

Our equipment is also capable of performing 4-D ultrasound, which has applications in fetal imaging.
