ultrasound Introduction 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 .
How Ultrasound Works 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.
