What Student Need To Know About Ultrasound Imaging In Radio Diagnosis

Ultrasound imaging (sonography) uses highfrequency sound waves to view inside the body. Because ultrasound images are captured in realtime, they can also show movement of the body s internal organs as well as blood flowing through the blood vessels. Unlike Xray imaging, there is no ionizing radiation exposure associated with ultrasound imaging. In an ultrasound exam, a transducer (probe) is placed directly on the skin or inside a body opening. A thin layer of gel is applied to the skin so that the ultrasound waves are transmitted from the transducer through the gel into the body. The images can provide valuable information for diagnosing and treating a variety of diseases and conditions. Most ultrasound examinations are done using an ultrasound device outside your body, though some involve placing a device inside your body. There are two main categories of ultrasounds: pregnancy ultrasound and diagnostic ultrasound.
