Two reasons. Firstly, Safety. Fetus have a higher rate of cellular division than the average human being. A damaged gene while still developing can cause birth defects. Secondly, X-rays really only give an idea of bone structure and generally aren't live. It X-rays don't give as clear an indication on lung and heart development.
Ultrasound is used instead of x-rays when applicable because there is no radiation exposure using ultrasound. There are also certain measurements and information obtained during an OB ultrasound and those things can not be evaluated on an x-ray image.
The sonic waves of ultrasound carry much less energy than those x-rays, that are almost as energetic as radioactive rays. X-ray is therefore, compared to ultrasound, somewhat more dangerous and its usage should be avoided, especially when very sensible organic material like an unborn child is concerned.
Ultrasounds are much safer for you and especially your child, with an ultrasound you can view various things such as the childs external and internals, they can also be used to monitor blood flow and heart beats, generally its much better but doesn't penetrate as easily as an x-ray.
X-ray has much better penetration however it's not as live as an ultrasound, you have to constantly keep taking x-ray photos in order to find exactly what you're looking for generally, unpractical even for a professional photographer what if you miss what you're looking for? You have to take more x-ray photos, the more you take the more radiation you and your child are exposed to. This isn't used in common pratice.
xrays are more dangerous than ultrasound
an ultrasound wave is used because the ultrasound is not a harmful to the baby as an xray....you can alson see a live picture with ultra sound
It can damage the cells in the body of mother and baby also it is much clearer.
X-ray is a tiny bit dangerous, particularly to babies. Ultrasound is considered safe.
The rule for x-ray is only to use it when it'd be a bigger risk not to.
Typically, a prenatal scan indicates having a sonogram/ultrasound performed. This scan can determine the baby's heart rate, size and weight and is a better predictor of gestational age. After week 20, expectant parents often are able to ascertain the sex of their unborn child through ultrasound.

It is an ultrasound scan.
An ultrasound tech will look for a penis or testicles when checking an ultrasound scan for a body. These parts of the anatomy make themselves very apparent on a scan in males.
Ultrasound scan requirements vary depending on the type of ultrasound. For example, for a pregnancy ultrasound, the woman is expected to drink 4 glasses of water and not relieve her bladder for an hour before the scan.
