What is an ultrasound?

The technology of an ultrasound has been used to obtain a picture of the foetus for decades now. If you are wondering, ‘is ultrasound safe for my baby’, it is imperative that you know what exactly happens during an ultrasound test. Here is an outline of the process:

  • During an ultrasound, sound waves are passed through your body. The waves go through your body- skin, flesh and muscles, and through organs like the uterus. The waves then bounce off the body of the foetus, giving you an outline of the foetus itself.
  • This outline shows up on the picture that we are all eager to see. The echoes of the sound waves appear in the image on screen- this allows the sonographer to record the position of the foetus in the uterus and its movements within.
  • The length and frequency of the sound waves respectively indicate the type of scan being carried out and how far along you are in your pregnancy.
  • A small amount of heat may be generated in your body due to the ultrasound but nothing that is detrimental or harmful for the body.
  • Antenatal scans produce less than 1°C of heat, nothing that can potentially cause damage to the developing foetus. For the heat to take a toll on your baby, the temperature would have to rise by at least four degrees.

  • A 2D ultrasound refers to the most basic and routine scan that only gives you can image of the foetus. A low intensity of sound waves is administered across a larger surface of the abdomen to obtain a workable image of the womb. There is minimal heating involved which is absorbed by the body without any consequences.
  • A 3D ultrasound is available only in private clinics which translates a version of the 2D image into a three dimensional version. The power intensity for this remains the same as that of a 2D scan, carried out for a few seconds longer.
  • A 4D ultrasound test consists of capturing moving images presented in the form of a video. Presumably the intensity of power required for this test is more than the 2D and 3D tests. Even so, the doctors advice against this test only in the delicate first trimester. In case of complications, in later trimesters, the detailed information can help doctors identify the cause of the problem.
