Anyone here refuse all ultrasounds?

Ultrasound technology hasn't been proven safe. This includes the ultrasound scan (picture), the Doppler scan, and the fetal Doppler heart rate monitor. According to, long term risks haven't been studied and short term risks include heating up of fetal tissue and possible cavitation (creating bubbles inside the flesh). 
I just read that the U.S. fetal death rate is HIGHER than the US Infant mortality rate for the first time in history--do you think this may be due to the overuse of ultrasounds?
