Ultrasound
or sonogram images (much like sonar devices that enable submarines
to "see" underwater) were developed in the late
1950's as the ultimate in hi-tech.
For the
first time, doctors were able to diagnose potential problems
using non-invasive radio waves that were safely beamed to
a chosen target inside the body.
To say
that ultrasound revolutionized prenatal care might have been
an understatement - as doctors were suddenly able to either
view a healthy growing fetus or provide an early diagnose
of a known complication.
Today,
the use of real-time scanners and 3D technology have taken
ultrasound to an entirely new level, allowing expectant parents
their first "movies" of an unborn child. More importantly,
it gives doctors a clearer picture of normal fetal age, size
and growth.
Ultrasound
monitors progress and creates a timeline for growth
stages,
determining sex around the 5th month. Above, two sonograms
showing
the fetus at 8 weeks and, at right, 27 weeks.
