Ultrasound
technology
Basically, an ultrasound also named as sonography performed
in a diagnostic centre, is a medical assessment
that uses high-quality sound waves to obtain the live pictures of the interior
of the body. Sonography is generally used to help diagnose the causes of pain,
infection, and swelling in the body’s internal organs, and also to examine a
baby in pregnant women. During pregnancy, ultrasound is performed to monitor
the progress of a growing fetus and also to detect abnormalities or signs of
diseases. It does not use any radiations like X-rays or CT scans, which makes
it safe for both the baby and the mother.
Sonography is based on the same principles involved in the
sonar. When a sound wave hits an object, it usually echoes or bounces back. The
echo waves are measured, which helps to determine the distance, shape, size,
and consistency of the object. Sonography is also used to detect changes in
size, appearance, a contour of organs, tissues, vessels, and abnormal masses
like tumors etc. With the help of conventional ultrasound, the images in thin
and flat sections of the body can be displayed. Ultrasound technology also
includes 3D ultrasound that formats the 2D images to 3D images.
Ultrasound technology also includes the Doppler ultrasound also known as color Doppler ultrasonography .Pregnancy Doppler is basically a special ultrasound technique that
helps the physicians to visualize and evaluate blood flow through the arteries
and veins in the arms, legs, abdomen, etc. The movement of the blood cells
causes a change in the pitch of the reflected sound waves, which is further
collected and processed by the computer. The computer creates graphs or
pictures that represent the flow of blood.
Doppler ultrasound can be of three types
namely color Doppler, power Doppler, and
spectral Doppler.
Usually, people are concerned whether ultrasound is safe for
pregnant women and the babies or not, but sonography is used for ages and is
completely safe if performed by professionals following proper guidelines. If
still, you are doubtful, you can consult for ultrasound
