The popularity of Ultrasound Scanner
An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy, and and they can detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy.
Other common names:
Ultrasound scan
Abdominal Ultrasound
Sonography
Doppler Ultrasoun
Sonogram
Echocardiogram
Ultrasound imaging uses high frequency sound waves that pass through your body. The sound waves are reflected or bounced off internal organs and tissues, and the waves are recorded and displayed by a computer. Ultrasound imaging works on the same principle as sonar, a technique to detect underwater objects used by both ships at sea looking for submarines and anglers looking for fish.
Ultrasound scanners usually consist of a computer, video screen, and transducer. The transducer is a small, handheld device about the size of a bar of soap, attached to the scanner by a cord. The transducer generates the sound waves and detects them when they are reflected.
Most ultrasound exams are done by moving the transducer on your skin over the area to be examined. Some, however, are done inside your body (invasive ultrasound). For these, a special transducer attached to the end of a probe is inserted into a body opening.
Examples of Uses:
Ultrasound can be used to view, monitor, or diagnose
abdominal organs
the heart
blood flow
pregnancy
muscles and tendons
soft tissue of any part of the body
Because ultrasound provides real-time images, it also can be used to guide procedures, such as a biopsy, in which a needle is used to obtain cells from an abnormal area for laboratory testing.
