Difference Between Two Dimensions and Four Dimensions

The difference between two and four dimensions? Two-dimensional B ultrasound it is generally not three-dimensional, four-dimensional color ultrasound it is three-dimensional imaging, four-dimensional color ultrasound see more clearly, it belongs to three-dimensional, can image. Two-dimensional color ultrasound it is plane color ultrasound, with mathematics inside solid geometry and plane geometry is the same truth. General four-dimensional color ultrasound can image, you can see what the baby looks like, you can also see the baby's internal organs structure, the baby has no deformity. Two-dimensional color Doppler ultrasound is a plane color Doppler ultrasound, a section of color Doppler ultrasound, so two-dimensional and four-dimensional is different. General four-dimensional color Doppler ultrasound is a large row of abnormalities, it is recommended to be pregnant 22 weeks to 26 weeks or so to do, two-dimensional color Doppler ultrasound is usually called ordinary color Doppler ultrasound, every month can be done.
