2. 2D Ultrasound
This is a standard ultrasound which is used by doctors to know the condition of the fetus. This ultrasound uses a transducer device which is moved on the stomach and then it will produce the fetal picture in 2D quality.
3. 3D Ultrasound
This ultrasound type uses more sophisticated technology where it gives a more detailed picture so that the doctor can see height, width, and depth of organs and fetus. By using this ultrasound examination, a doctor can diagnose problems related to pregnancy. Even though it has the same procedures with 2D ultrasound, this 3D ultrasound uses software and special censor tools.
