It is a method that relies on the high-frequency sound waves that bounce off the objects and thus become images of them
The technique is mainly used in space programs but has been used in medical diagnostics such as prenatal care
One type of ultrasound, the senogram or beta, is a population in which the intermittent sound waves are channeled into the pregnant mother’s abdomen. The image of the fetus, placenta and other tissues carried by pregnancy is transmitted. This image is transferred to a video screen. In this way, the doctor can determine the size and position of the fetus, assess the development of the fetus, determine the presence of multiple pregnancies, placenta location,
Ultrasound is considered to be more effective and safer for the fetus than regular x-rays. Like all medical tests, it should only be performed if necessary.
