Whenever there is severe pain in any part of the stomach or the doctor has to know the reason behind it, then he has to resort to ultrasound or sonography. Ultrasound is a device that shows live images of the internal parts of our body. For this, sonar and radio technology is used.
Often you must have seen that doctors apply gel on the stomach before doing ultrasound. Such questions must be arising in the minds of many people that what is this and why is it needed? Can ultrasound not occur without it or does it only smoothen the surface? Let us know about it…
This is the reason behind applying jail…
While doing ultrasound or scanning, gel is used between the skin of the body and the probe. This completely eliminates small air particles between the transducer and the skin. Due to this, the possibility of air formation here becomes negligible. This reduces the acoustic impedance and radio waves travel easily between one medium and another. On hitting any tissue, some waves return to the probe and some go further. From there they collide with other tissues or instruments and come back. Because of this, we get to see a good image of the organs located deep in the body.
is safe for skin
This gel is made from water and propylene glycol. It is not harmful because it is completely non-toxic. According to radiologists, there is no poisonous substance in the gel which can harm the skin. It is because of the gel that the sensor of the transducer is able to move forward easily after making contact with the skin.
