Maybe I am old fashioned, but ultrasound equipment is designed for medical
testing. Medical testing (at least as I was taught) required that the
patient first be evaluated by a physician and then if deemed medically
necessary, medicatl testing would be ordered. In other words a physician
order was required before a patient could have a test. I know that the FDA
had closed many fetal ultrasound companies for using Medical equipment
(duplex imagers) for entertainment purposes (providing pictures of the
fetus). General screening is not "entertainment", but I am not sure how
they get around not having a physician's order prior to performing a medical
test using medical equipment. If they are not calling it a medical test,
then what are they calling it- I mean they state a physician interprets the
Just something to think about.
