The new generation of three- and four-dimensional ultrasound imagery provides striking views of fetuses inside the womb. Parents-to-be appreciate the lifelike pictures, and doctors gain an improved understanding of fetal development and behavior.How is Planned Parenthood and NARAL going to spin this into their "its just a blob of tissue" nonsense now??
Four-dimensional imagery shows objects in 3-D moving in something close to real time. Doctors have long known that fetuses move, but the physical behavior revealed by 4-D scans is expanding that knowledge exponentially.
"We see the earliest movements at 8 weeks," Campbell said. "By 12 weeks or so they are seen yawning and performing individual finger movements that are often more complex than you'll see in a newborn," he said. "It may be due to the effects of gravity after birth."
The images reveal facial expressions, like smiling, at 20 weeks. Beyond 24 weeks fetuses may suck their thumbs, stick their tongues out (perhaps using newly developed taste buds to sample amniotic fluid imbued with the flavors of the mother's food), and make apparently emotional faces.
The culmination will be when someone uses this technology to record an abortion being performed; grizzly but effective.
How would that be for Reality TV?
