History of the ultrasound

The first in the search sonar since 1822 when he sought the Swiss physicist (Daniel Kuladin) to calculate the speed of sound through water Jursh in the waters of the Lake (Geneva). Which paved the way for the development (the theory of sound) in the 1877 efforts of the world (Lord Relih), which explained the basics of the physical sound waves and the transmission and apostasy. Continued until the research was the design and create the first system (Sound Navigation & Ranging) Sonar working in the United States in 1914 by the World Fsndn for the purposes of navigation and to determine the German marines in the First World War.
That the patient was fully or partially engulfed in the water
Did not employ ultrasound for medical purposes until the beginning of the forties, by Dr. nerves, Austrian psychiatrist (Carl Theodo), which was the first doctor used ultrasound in medical diagnosis has been faced with difficulties due to the absorption of the bones of the skull of the most energy ultrasound.
After the outcome of intensive efforts to Vesiaiien mechanics, engineers, electricians and biologists in collaboration with doctors and computer programmers, researchers and government support, began to diagnostic ultrasound to take place in clinics, nerve, heart and eyes and develop a spate of A-Mode is limited to the use of B-Mode, which sought the world (Douglas Huree) ray technician for use in diagnosis for their ability to penetrate the tissue in order to study the anatomy of the body at the University of (Colorado) in collaboration with his colleague Dngr kidney specialist (Joseph Homless), which in turn built the medical research at that level, the guidance and cooperation of scientists and engineers (Bales and Boscconne) was the first of a two-dimensional Oltrasaund working with B-Mode in 1951
Continued working in the organs of the system, but they were all large and the patient to engage in whole or in part, the status of water in the stillness of the long period of time which make it impractical and impossible it is in the clinics of jurisdiction.


Mobile metal arm
In late 1955 the world began the development of these devices to become more sensitive and smaller and more easily in the way they test, even the metal arm of the wheelchair and put on the place for examination, as was development of the vaginal and anal Aloltrasaund 1955, which operates A-Mode system, the efforts of the Worlds (Wild ) and (Reid), but at this stage did not achieve the actual purpose was developed until later, all of these developments has experienced great success and took place in a large part of the world such as the United States of America, Austria, Japan, the United Kingdom, which paved the way and opened the way for the entry of a Aloltrasaund devoted to gynecology and obstetrics, and thus the start.
It is manned on Aloltrasaund for this specialization, Dr. England (Iain Donald), which is leading efforts in this regard began with the way the diagnosis clusters fiber surfaces, whether or tumors, or even paper bags and left the work was one of the greatest highlights ten medical

Ian Donald
The past year of collaborating with the art world (Tom Brown) and Dr. (John Makvekar) in 6-7 / 1958 and in 1959 was able to pick up the echoes of a clear head and then the fetus has become the dimensions of the area around the head of the fetus is the means adopted to study the growth of the fetus. And after a few years they could have been studying since the beginning of pregnancy until the end, and the diagnosis of many problems, such twins, congenital malformations and the problems associated with the placenta.
It was not before 1972 could be seen and to study the vesicles with B-Mode at the hands of the Austrian World (Kratochwil) and thus become Ultrasonography in gynecology and obstetrics arena for competition among specialists and increased research and papers from a single research paper, Dr. (Iain Donald) in 1958 to 296 A working paper in 1978.
In this intensive efforts of doctors able to diagnose the age of carry bag 5 weeks in 1963, and to identify the pulse of 7-week-old fetus in 1965 and in the seventies it was possible to measure the perimeter of the head of the fetus and the area around the chest, which played an essential role in following up the growth and development of the fetus and detect any inhibition of growth, and the calculation of the length of the fetus and the area around the abdomen through which the scientists were able to get an idea of the weight of the fetus and the conditions of nutrition.
The holes were diagnosed pm (Spina Bifida) and the disappearance of the head in the fetal skull (Anencephaly) in the seventh week of pregnancy. All of those developments were not to be found in B-Mode and enter the shades of gray bodies Aloltrasaund after it was in black and white, and this gave Aldrgip in color and clarity of the picture has become the focus of scientists to increase Aldrgip to increase the accuracy of the examination.
With the eighties there have been a real revolution in the world of ultrasound, a so-called (Real time scanner) imaging of any district (two-dimensional B-Mode), which was on its way to identify the actual life of the fetus, and actions, and actions, and a heartbeat, and breathing in the womb of the mother. The first effective system in this area in 1985 in Germany, and the eighties is the field of competition for the manufacturers of the devices Aloltrasaund to provide the most accurate and clearest images. Thus took shape in the new flag, gynecology and obstetrics devoted (diagnosis and the safety of the fetus).


Aloltrasaund vaginal device in the first, whose beginnings have
The system has been developed Aloltrasaund vaginal and anal, which was designed for the first time at the hands of (Reid) and (Wild) in 1955, this development has taken about twenty years to be effective and achieve the aspirations of scientists in the detection of the internal organs of the basin and the spread between the medical profession.
The year 1985 is the year that embraced more devices and the effectiveness of vaginal Aloltrasaund greatest interest, has coincided with the development of the first in vitro techniques in Austria.
It is technology, which lasted a long time, even ridiculed the use of actual Aldoblar ((Doppler and (M-Mode) The principle of Aldoblar was the first de******ion of the efforts of the development of a world Austrian (Doblar Christian) in 1842 and began applying the Japanese in 1955 to study the movements and heart valves. In 1962, using Aldoblar scientists tracking the flow of blood and fetal pulse and devices developed in the investigation of the flow of blood to become a two-dimensional and able to follow the living color of the functioning of blood ((Real time Color Flow Imaging.


Doblar system in the first, whose beginnings have
The eighties and early nineties the scene of the great progress made by the manufacturers of the devices Aloltrasaund two-dimensional, as these devices become the mainstay of incorporation of any women's clinic and the generation and helped in the sense of scale and Odhirap examination and that occupy a narrow space on the body and gives a wide range of vision in addition to the free movement of such devices.
Most importantly, the fine details of these organs, which examined the image and clearly identify the features and accurate diagnosis so that the organs of Aloltrasaund was ranked first among the means of diagnosis, which was not limited to diagnosis, but was surpassed by the body to examine the internal organs of the embryos in the mother's womb to become the majors, but in its own right.
After the long stages in the History of ultrasound, after the revolutions of the flag burning at every level and with the requirements of the age of renewable approaching the second millennium and the computer in close association with all human movements no matter how small, has become two-dimensional devices Aloltrasaund unsatisfactory - in spite of all the success of - and diagnosed with the eyes of scientists about the third dimension, which failed on the two-dimensional devices get to the bottom and the idea was looming on the horizon since the seventies, they started to focus and take the dimensions of the beginning of the eighties and supported the greatest technological revolutions and its presence in computer programming.
In Japan, at the University of Tokyo was the first report on the three-dimensional (length, presentation, depth Ooalaratvaa) in 1984 and the first successful attempt to obtain three-dimensional image of Jenin, two-dimensional image through the computer was in 1986.
After the development of Turasaund independent three-dimensional problem in the time it takes to take each section, where more than ten minutes, making it impossible to work both for the patient or the treating doctor, and therefore impossible to marketing. With the intensive efforts and the continued development was the first of a three-dimensional take Turasaund shops in the market in 1989Combison-330)) in Austria and continued to the world, especially in Japan, Austria, Britain, Canada and even China in advancing the development of this research has also begun on a four-dimensional in London in 1996 when it emerged the idea of living three-dimensional imaging and after the fourth dimension of time, its role in giving the true picture of living a practical way, and that was to be no dramatic developments in computer science and the enormous speed in a computer operations, hence the
The story of the beginning
