Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small probe and ultrasound gel placed directly on the skin. High-frequency sound waves are transmitted from the probe through the gel into the body. The probe collects the sounds that bounce back and a computer then uses those sound waves to create an image. Ultrasound examinations do not use ionizing radiation (as used in x-rays), thus there is no radiation exposure to the patient. Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Conventional ultrasound displays the images on computer monitors for interpretation by a radiologist. We have the most advanced ultrasound technology including three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images.
