The first
ultrasound
equipment was developed in 1955. diagnosis was tested on several
occasions the researchers around the world and had decided to be a
reliable and safe.It has become very popular and nowadays it is hard to
imagine modern medicine without ultrasound.After 2D ultrasound
3-dimensional devices appeared in 1989 in Austria.
Ultrasound is a widely used technique in all areas of medicine, but many
people are either ignorant of the nature of the technology or the wrong
idea about it. It is not unusual to find people to put in the same
group as the x-ray. This false impression may understandably raises an
important issue, especially if the pregnancy is at risk. Let's start
with that simple but important act. Ultrasound does not involve ionizing
radiation.
Ultrasound is part of the sound spectrum that ranges from about 20 kHz to 10 MHz and can be divided into three main regions
This will be in the range of 3.5 to 7 milion cycles per second (Megahertz).
normal sound waves are audible to the ear with a much lower frequency of less than 20,000 cycles per second.
Ultrasound
is a form of sound waves generated at very high frequency.The level of
frequency is inversely proportional to the power output. High power, low
frequency
ultrasound does alter the state of the medium and is the type of
ultrasound typically used for sonochmical applications .
Sound
waves to produce crystal built probe used for the test. Sound waves are
then reflected in the various structures they encounter they pass
through the body.Information produced by reflected waves will then
consider your scanning machine produces an image on the screen
representative of the reflecting structures. That is how the detailed
image of the pregnant uterus and baby within, complete with movements,
is produced and seen in real time.
There may be a slight annoyance to a full bladder pressure, otherwise
the procedure is completely painless. Conducting gel may feel a bit
'cold and wet. There is no perception of the sound waves and of-course
you cannot hear them.
Types of ultrasounds
There are differences in the types of
ultrasounds
done in pregnancy. Many types of ultrasound tests that vary depending
on the body part being examined, but the basic process remains the same.
( 1 ) 2D ultrasound
for future parents is the temptation to see the baby like in real life,
in color, look into the eyes and try to understand to whom he looks
like most.
2D Ultrasound
gives you the edge and flat looking image, but can be used to view
internal organs of the unborn baby. This is useful for diagnosing heart
defects, kidney problems and other affairs.
( 2 ) 3D Ultrasoundsit becomes possible to see some structures that are difficult to study in 2D mode.
3D Ultrasounds are used to show images in three external dimensions, which may be useful for diagnosing problems such as cleft lip.
( 3 ) 4D Ultrasounds Is Advance Feature of 3d and 2d mode.Now You Can See Live Video and Colorful pictures of the unborn baby in the womb.
4D Ultrasounds allow us to view unborn babies as never before.
3D Ultrasounds and
4D Ultrasounds are useful modality that particularly benefits women's health During Pregnancy and obstetrical care in the developing world.
3D Ultrasounds and
4D Ultrasounds
is amazing technology .See your unborn baby up close and personal. I
would recommend it to especially pregnant women’s. This experience would
be incrediblly amazing, and unforgettable.
