Ultrasound- A Noninvasive Technology is Performed by Sound Waves
Ultrasound imaging or sonography is an imaging technique that uses cyclic sound pressure with high frequency. Such sound waves are able to produce pictures of the inside of the body. Though ultrasound is used in many fields, typically to penetrate a medium and scale the reflection signature or supply focused energy. This reflection signature can show the inner structure of the medium. The same technique is applied to produce pictures of fetuses in the human womb. Such illustrated pictures can show the movement of the internal organs as well as blood flow through the vessels.
The advanced ultrasound technology can produce three-dimensional (3-D) images and four-dimensional ultrasound is 3-D ultrasound in motion. Such imaging is used in the noninvasive medical test that helps doctors to diagnose and treat medical conditions. Unlike X-ray and CT scan, there is no ionizing radiation exposure with the test. A water-based clear conducting gel is applied to the skin (that is to be tested) to help with the transmission of the sound waves. A transducer is moved over the area being examined.
Medical sonography is an ultrasound-based diagnostic technique that can be used to visualize internal organs of the body. The images enable to capture their size, structure of the body parts with real time tomographic images. There is an advanced ultrasound technique called Doppler ultrasound that can evaluate blood velocity flowing through the blood vessels. It can be categorized into three types such as Color Doppler, Power Doppler, and Spectral Doppler. There are some important components of the ultrasound exam, such as sonographers and ultrasound technologists, central procession unit, transducer pulse controls, dick storage, display, keyboard/cursor, ultrasound printers.
Ultrasound technology helps to diagnose a several disease and to evaluate symptoms like pain, infection and swelling. The use of prenatal ultrasound is very popular to view the condition of child during pregnancy. Its use in the routinely scans include musculo-skeletal, endocrinology and otolaryngology. Such scans are usually painless, less expansive and easy-to-use.
