                <p><strong>Ultrasound in pregnancy</strong> (also known
as 'sonograms' or 'scans') can be performed for a variety of reasons.
Medical ultrasounds in pregnancy work on the same principle as sonar
(used in oceanography to map the sea bed). The technician uses a hand-
held ultrasound probe (or 'transducer') to generate and receive high
frequency sound waves that cannot be heard by the human ear. Hundreds of
sound waves are emitted from the transducer during each scan. These waves
are absorbed and bounced back from human tissues, bones and body fluids
(all with different densities) to create black and white ultrasound
images that look similar to a photographic negative, with black areas
indicating liquid mediums (such as amniotic fluid) and grey or white
areas indicating denser materials such as tissues and bones.</p>
<p>The sound frequency of ultrasound is measured in megahertz (or MHz).
Frequencies used for pregnancy ultrasounds can range from 1.6 to 10 MHz,
but are more commonly between 3 and 7.5 MHz. Generally the lower the
frequency, the further (or deeper) the sound waves can penetrate the
body's tissues. Ultrasound waves that create images for visual
examination are intermittently 'pulsed' to reduce the heating of the
body's tissues (unlike continuous ultrasound therapies that may be used
to treat injured muscles and tissues). 'Diagnostic ultrasounds' (that
create images) tend to require lower intensities than Doppler ultrasound,
used to assess blood flow through the cord and placenta and to listen to
the baby's heartbeat. Ultrasound does not use radiation (like x-rays) and
is seen by many caregivers as a non-invasive way to view the unborn baby,
uterus and placenta during pregnancy. The physical effects and research
into the safety of ultrasounds are looked at in <a rel="nofollow"

href="http://www.earlyimage.com.au">Ultrasounds in pregnanc</a>y are
performed by a qualified Sonographer (technologist) or a Sonologist
(specialist doctor). Usually the Sonographer performs the examination and
the Sonologist in charge of the department interprets the images and
writes up the final report.</p>
