What is Sonography: How it Works, Tests, Best Programs 24

What is Sonography

Sonography, also known as ultrasound, is a diagnostic imaging technique that uses sound waves to produce images of internal organs. The images can be used to help diagnose and treat medical conditions.

Sonography works by sending sound waves into the body and capturing images of internal structures. These images are converted into electrical signals that are used to produce images on a computer screen.

There are different types of sonographic exams, including abdominal, obstetric, pelvic, and vascular sonograms. Each type of test uses different techniques and equipment to produce images of specific organs or areas of the body.

Most sonographic examinations are performed on an outpatient basis and do not require any special preparation. However, some tests may require you to fast for some time before the test or drink plenty of fluids so that your bladder is full.

During the exam, you will lie on a table while the technologist applies gel to your skin and moves a hand-held transducer over the area being imaged. The transducer emits sound waves that travel through your body and bounce off your organs. The reflected sound waves are captured by the transducer and converted into electrical signals that are used to produce images on a computer screen.

How does Sonography Work

Sonography uses high-frequency sound waves to create images of the inside of your body. It is great to see the soft tissues of the body through this and it often helps determine the cause of your symptoms.

Sonography imaging uses a small transducer to both transmit sound waves into the body and record the waves that echo back. The sound waves travel across the area being examined until they hit a boundary between tissues, such as between fluid and soft tissue, or between soft tissue and bone. Some of the sound waves at these boundaries are reflected back to the probe, while others travel until they reach another boundary and are reflected back. The speed, direction and distance the sound waves travel vary depending on the extent, a computer interprets this information as a screen image.

The intensity and size of the echoes depend on how the area absorbs the sound waves. For example, most waves pass through a fluid-filled cyst and send back very few or faint echoes, which appear black on the display screen. The waves, on the other hand, bounce off a solid tumor, creating a pattern of echoes that the computer interprets as a light-colored image. It is also observed that air and bone also reflect sound waves.

Today ultrasound has been around for over sixty years and is considered safe because it does not appear to have any known risks and does not use radiation. It is one of the most commonly ordered imaging tests because it is versatile, portable, relatively inexpensive, non-invasive, and can provide real-time information about the area of ​​concern.
