The ultrasound scanner is a medical device that uses high-frequency sound waves to capture real-time images of the body. The image is called a sonogram.
This technology is similar to the technology used in sonar and radar to help the military detect aircraft and ships. The sound waves emitted by the ultrasound scanner allow the doctor to view organs, blood vessels and tissues without surgery.
Most people associate ultrasound scans with pregnancy, which provides a first-eye view of the fetus for pregnant women. However, ultrasound scanner have many other uses. For example, they can find problems with the liver, heart, kidneys or abdomen.
How do sound waves capture images?
ultrasound scannerwork by sending high-frequency sound waves to the patient. Sound waves pass through the patient’s body and pass through different types of tissue.
For example, ultrasound will pass through the blood in the heart chamber, but if it hits the heart valve, it will produce an echo or bounce.
If the sound wave does not find gallstones, it will pass directly through the gallbladder, but if there are stones, it will rebound.
The higher the density of the ultrasonic impact object, the more the number of ultrasonic bounces.
The resulting bounce or echo provides a feature for the ultrasound image. Different shades of gray reflect different densities.
ultrasound scanner are commonly used for diagnosis, treatment, and guidance during procedures such as biopsy.
Can be used to check internal organs such as the pancreas, liver and kidneys, thyroid and ovaries.
Ultrasound scans can be used to check whether the mass is a tumor, or cancer, or a fluid-filled cyst.
It also diagnoses problems with muscles, soft tissues, blood vessels, joints and tendons. It is used to check for frozen shoulder and carpal tunnel syndrome.
