A new generation of magnetic scanners

Public MRI scanner "Unitom" was created by Russian scientists

A magnetic resonance imaging, available in any remote region, every Russian and any income - Public MRI scanner "Unitom"! Preparing mass production of devices.

Detector business unit MRI - one of the most innovative and effective in the diagnosis of medical devices. With it, identifies hundreds of diseases, including early. The whole world has long recognized its numerous advantages over X-ray apparatus. But what we see in Russia? Millions of people exposed to the X-ray during the survey. Equipment, invented in the nineteenth century, can be found in virtually every district hospital in Russia, while the innovative magnetic resonance scanners in our country only about 450 pieces. With a population of nearly 150 million people.


If you consider that all Russians must pass medical examinations at least once every two years, CT scanners in Russia, the most common estimates, should be at least 10000 pieces.

Make MRIs available for each district hospital in every distant corner of Russia - it is possible today. But not through the purchase of vehicles abroad at fantastic prices. "Screwdriver assembly" of foreign counterparts - not a solution either. On this did not have enough funds or technology to solve the problem of global scale.

The organization of mass production of affordable home scanners, scanners that is the People in Russia - that's the problem. What, then, should these new devices? First of all, it should be imagers that can afford to establish not only the regional and provincial centers, but also small local clinics. In fact, the scanner must be accessible to the population of Russia as a normal x-ray machine. It will raise the early diagnosis of disease to a new level, and mortality from disease is significantly reduced.
This Public MRI scanner Group of Companies was created by experts, "Control" and named "Unitom." Overall, this is the result of 30 years of research in the field of magnetic imaging. A number of original technical solutions protected by 16 patents.

The world's first fully digital magnetic scanner . Suffice it to say that in a second measurement is recorded and processed one billion bits of data in real time. The use of the latest technological advances brought results: obtained image quality is not worse than on costly foreign imagers . Prices of the last times and reach 160 million rubles. The problem of high prices has become known throughout the country thanks to the president's robust language.

Sravnite prices MRI scanner


This high field magnetic scanner requires a lot of money for their upkeep. Liquid nitrogen and liquid helium needed to operate the scanners using superconducting magnets, virtually inaccessible in remote regions of Russia. Requires a separate discussion of these extremely high energy CT scanners - 60-100 kVA.

Public MRI scanner - scanner "Unitom" - no need for expensive cryogenic materials for his service . He is the most "green" scanner: its power consumption compared to foreign energy high field scanners below 100 (!!!) times. So, scanner can be powered by solar panels, even ! The size of the room where you can set the "Unitom", a fraction of the size of the room required for the traditional foreign MRI. Also, thanks to the many innovative solutions, Public MRI scanner is only 6 million rubles .

If we imagine an analogy from the world of cars, our scanner would be a machine worth 10,000 rubles, and consumes 1,000 kilometers a liter of gasoline. This can really surprise the world.

Detector "Unitom" has successfully passed the clinical and technical tests, has all the necessary permits, has more than one hundred patients in real practice. received 30 000 tomograms . Numerous advantages of the scanner "Unitom" to foreign analogues confirm eminent scientists, doctors, including SB RAS, MSU, MIPT . Applications for the purchase of the imager "Unitom" are derived from more than 40 countries are negotiating co-production with the Public MRI scanner National Research Council of Canada.

Management of our state is looking for projects throughout the country, which could lead Russia to a new level of innovation, as well as create thousands of new jobs in high technology. Here is an example of such a project. The biggest innovation risks we took for himself scanner has been created without the involvement of the budget. Nevertheless, the State constantly spending money to buy scanners abroad, and not to similar projects. Thus, in essence, virtually closing the market for Russian producers. In turn, it is obvious social project. Mass production of high-tech medical equipment in Russia - this is the problem of national significance. However, it is possible to establish a production and, without government support. The only question is when and in what country?

On the basis of "Unitom" we propose to begin mass production of the Public MRI scanner. To achieve this goal and created an open source project "Public MRI scanner." The project is open, as it involves the creation of productive cooperation, which can take part in almost every.

Mass production scanners People will be done by SKD domestic production of components built by Russian companies. In this case, in accordance with which we developed the technology unit will be collected directly at the place designated by the customer. This will involve the production facilities across the country.

In other words, the organization, participating in co-operation to establish the Public MRI scanner will be mass-produce some portion of the apparatus. For this she receives the right to produce a certain amount of self-scanners, of the components of vehicles made by other organizations. Thus, each of the companies involved in co-operation, would be interested in the quality and timely delivery of equipment for the project . If the same firm involved in the project will need to release more CT scanners than is definitely mutual, it can make additional payments under the license agreement and will be able to put on the market as many vehicles as necessary. At the same time MRI scanner in the end need not be identical.

If you want to participate in the project "Public MRI scanner", please contact us at control@ controlgroup. ru We are waiting for suggestions, especially from companies that have experience in:

We look forward to working with you!

Ответы на вопросы по статье о Народном томографе в "Российской газете"

There are no translations available.

После выхода в свет статьи «Почем томограф?», опубликованной в «Российской газете», на наш сайт приходит много писем с различными вопросами о Народном томографе. Сегодня мы публикуем интервью, данное вдогонку к статье в «РГ» руководителем Группы Компаний «Контрол» Крутских Валерием Ивановичем редактору сайта "Омскмама" Борису Сухорукову.

Борис Сухоруков: Здравствуйте!

Уважаемый Валерий Иванович, пожалуйста, помогите разобраться в теме!

Ваш прототип Народного томографа – томограф «Юнитом» - является низкопольным оборудованием, а России нужны и высокопольные томографы, которых вы не делаете. Могли бы вы разъяснить этот вопрос. Если я правильно понял ваше интервью в «Российской газете», то ваш прототип, хоть и имеет низкое поле, по эффективности МР-обследования его можно приравнять к высокопольным импортным томографам. Как здесь разобраться? Могли бы вы доступно объяснить, какие импортные томографы (с указанием силы поля) может заместить ваш томограф.

Валерий Крутских: Вопрос действительно непростой, к тому же людей вводит в заблуждение реклама.

Я постараюсь объяснить ситуацию на простых примерах.

Когда Вы идете покупать в магазин продукты, например хлеб, Вас мало интересуют вопросы, где растили зерно, мололи муку и по какой технологии выпекали хлеб. Прежде всего Вы заинтересуетесь, вкусный ли он, свежий ли он, какова его цена, как долго его можно хранить и где? Важным для вас будем и место расположения булочной. Если за хлебом надо будет ездить из Омска в Москву, Вам это вряд ли понравится. Вот в томографии точно так же. Прежде всего, надо смотреть - может ли врач правильно поставить диагноз по томограмме. Качество томограмм народного томографа не вызывает сомнения, даже человек далекий от медицины может это оценить. http://krutskikh.livejournal.com/431.html

Для специалистов качество томограмм официально подтверждается техническими и клиническими испытаниями. Только после их успешного прохождения Комиссия по новой технике Минздравсоцразвития рекомендует томограф для серийного производства и включает томограф в официальный список медицинского оборудования. Все эти необходимые документы народный томограф имеет.

Более того, в реальной практике получено 30 000 томограмм, и не было ни одного случая жалобы пациентов на неправильный диагноз.

Теперь цена. Мне не очень нравится словосочетание "дешевый томограф". Здесь как-то всплывает ассоциация - дешевый значит недостаточно хороший. Больше подходит - "доступный томограф". Это как хлеб, он должен быть доступен по качеству, цене и месту покупки.

Если припечет, Вы, конечно, будете покупать хлеб по цене черной икры и в Москву ездить будете, как раньше ездили за колбасой.

Если хлеб будет недоступен, то вряд ли Вам это понравится.

Именно так сейчас происходит и с МРТ томографами в России. Они малодоступны большинству населения и сосредоточены в больших городах. Только недавно Голикова наконец раскрыла "большую государственную тайну" - в России всего 450 магнитных томографов. Для примера, в США - 30000 и планируется выпустить еще 10000.

Когда-то Мария-Антуанетта предложила кормить голодных. людей пирожными, если нет хлеба. Так и наши чиновники от медицины расхваливают и закупают высокопольные томографы со сверхпроводящими магнитами. В действительности, людям нужны и хлеб и пирожные. Беда в том, что хлеба нет, а пирожных очень мало.

Да, только в МРТ томографах с высокими магнитными полями можно делать уникальные исследования по функциональной магнитной МРТ томографии, но в задачах стандартных обследований - так называемого скрининга, народный томограф не уступает ни в чем и даже имеет лучший контраст томограмм. Кроме того, он безопаснее. Реклама высокопольных томографов никогда не говорит о вредном влиянии очень мощных радиочастотных импульсов и градиентов магнитного поля. Например, томограф с полем 3 Т уже не проходит по европейским меркам безопасности, но, в виде исключения допускается в клиники. Даже человеку, далекому от техники, интуитивно понятно, что если один прибор - народный томограф, потребляет 500 Вт, другой – высокопольный - 100 000 Вт, то эта энергия по разному воздействует на пациента, находящегося внутри томографа.

Переходя к более профессиональным терминам, можно сказать, что каждый тип томографа занимает свою нишу, но сверхпроводящие томографы не смогут стать доступными в любой районной больнице, такими томографами нужно оснащать крупные больницы и медицинские центры для исследовательских работ.

К сожалению, в России сейчас нет технологий, необходимых для выпуска сверхпроводящих магнитов.

 

How much scanner?

In Russia, the apparatus was much cheaper to import

No secret that one of the main causes of a scandal with the purchase of imported scanners - their price. It's tens of millions of rubles, and so on pullbacks can be a very decent money. But few know that Russia in 2000 could refuse to import this medical equipment.

We have already had a scanner. Its price - a total of 6 million rubles, as in conventional X-ray machine, which is much cheaper than the imported machines. The authors gave him the name "Unitom" and another called "folk." Because at this price it is quite expensive for ordinary clinics. But now in the court in 2011, and the scanner for the people and stayed in a single copy.

May be to blame for the well-known conservatism of doctors? Maybe the name manufacturers worked? On the one hand, there are such giants as "Siemens", "Toshiba", "General Electric" and the other a kind of an unknown Russian company ...

"Unitom" is really capable of hitting. Most importantly - it does not require complicated and very expensive system with liquid nitrogen to create superconductivity. Professionals that seems unbelievable: how else can get a strong magnetic field. It provides the highest picture quality of human body. And all over the world seek to enhance the field in many different ways.

- We went the other way, the field does not increase, and vice versa - reduce - explains the Doctor of Physical and Mathematical Sciences Valery Krutskih. - How did this paradoxical idea? You know, among those who stood at the origins of imaging, marked and then the Nobel prizes, there were many physicists in the field of so-called nuclear magnetic resonance spectroscopy, which has a unquestionable axiom: The stronger the magnetic field, the better the resulting image. Hence the purpose of development: a strong, even stronger. Now the magnetic field has reached a 11 Tesla. But what's good for spectroscopy, is not ideal for humans.

Krutskikh noticed: the more magnetic field scanner, the more energy that is radiated by the device absorbs the body. Moreover, the image quality only initially increases in proportion to the magnitude of the field, but at some point saturation. An increase of almost no gain in the image. But it distorts the growing "noise" - a variety of interference. And here Krutskikh saw his chance. We should not strive for a strong field, and reduce the "noise". All possible means. It turned out that this virgin land.

- We are gradually brought his scanner, - said Valeriy. - For example, instead of analog signal processing applied digitally and immediately eliminated all the 'noise' that makes electronics. Changed the design and materials of the magnet, thus repeatedly to reduce energy waste and harmful interference. Invented a new system for receiving a signal coming from the human body, which is at the World Exhibition of Inventions in Bulgaria won the gold medal. In addition, much improved processing algorithms derived in MRI data.

Word, in fact, each node device has been developed from scratch. Which took almost 20 years. And a penny from the public purse. The device was created by means of the authors. Krutskikh achieved his goal, his scanner with a weak magnetic field gave the same picture quality as conventional vehicles of the "legislators" tomographic fashion. But "Unitom" got rid of superconductivity, and worked from the usual outlets, consuming only 0.5 kW instead of 100. And there was a lot cheaper.

Device has passed all the circles of clinical trials. We gathered a voluminous Krutskikh folder of correspondence and the positive findings, signed by eminent scientists and Medical Sciences Academy of Sciences, in particular, the Chairman of the Scientific Council of the International Tomography Center, Siberian Branch of RAS Renad Sagdeev. Moreover, chief of radiation diagnosis of Moscow, Yuri professor of Warsaw gave its approval for mass production. Commission on New Medical Technology Ministry of Health has set to recommend "Unitom" for mass production, he was even given a registration number. And when it seemed that all barriers are overcome, it stalled for more than 10 years. According Krutskikh all depends on the Ministry of Public Health, who declares that he is such a device without the need to. Recently

History with the Public MRI scanner came out for the next round. He was listed as a innovative proposals of Sciences and accepted for consideration by the Commission under the President of Russia's modernization and technological development of economy. However, the Health Ministry again denied it, citing the fact that this scanner magnetic field is smaller than that of imported vehicles. It turns out that officials do not understand what is unique is the essence of the invention.

- But we are stubborn as a rhinoceros, go ahead - laugh Valery .- Now consider the proposals of several companies from Omsk, Vologda, Dubna, Troitsk, who are ready to begin production of the imager. He already has on the application from almost 40 countries, in particular India, Pakistan, Iran, Iraq, Syria, which bulk purchases of traditional expensive technology can not afford. So the market is huge, and I am sure that the "Unitom" is sure to be in demand.

Way, recently reflected on the Public MRI scanner, even the Americans, where today there are about 30,000 such vehicles (in Russia only 450). U.S. Department of Health has provided the company "General Electric" grant to develop within three years, the concept of cheap magnetic imager.

without X-ray

Magnetic resonance imaging (MRI) produces images of internal organs without using X-rays and radiation. Scanner measures the electromagnetic response of nuclei of hydrogen atoms to excite them with electromagnetic waves in a magnetic field.

The method of four Nobel Prize. In 1952 it received Bloch and Purcell in the discovery of magnetic resonance in 1979, Cormack and Hounsfield for their work on reconstruction tomography, in 1991, Ernst was awarded the Prize for Chemistry for his achievements in the field of magnetic imaging, in 2003, Mansfield and Loterbur for research opened the way for imaging in medical practice. Tomography allows visualization of high-quality head, spinal cord, cardiovascular system and other internal organs, to detect early cancers.

Yuri Medvedev, "Russian Newspaper"

 

Remember, mourn

 

 

December 31, 2010 at 76, died d f.-m. Mr., prof. Petrusevich Luzhkov. As a deputy. Head of the Department of Medical Physics, Physics Department, Moscow State University. Moscow State University, he was in the Coordinating Council of "Public MRI scanner." We bring our condolences to the family and friends of Yuri Mikhailovich.

 

The advantages of low-field magnetic resonance imaging (MRI)

Diagnostic image quality of magnetic resonance imaging (MRI) is fundamentally determined by the ratio of the observed values ​​of contrast fabric and the noise level. While the absolute magnitude of the signal decreases monotonically with decreasing field strength, the contrast, defined as the relative difference inintensity of adjacent tissue, in contrast, increases because of the divergence of relaxation times. On the other hand, the observed noise includes terms that are generated by the object under study (the patient's body) and radio-electronic components of the device. At low fields, the noise contribution of the object is negligible, which helps to reduce overall noise levels by improving the electronic scanner. The combined effect of these patterns leads to the fact that the optimum contrast ratio S / N (in the study of central nervous system) is observed in magnetic fields below 0.5 Tesla.

 

Why need a low-pass scanner?

1. Magnetic resonance imaging (MRI) is necessary, primarily for the detection ofvarious pathologies of the human body. Biophysical studies have shown thatmeasured values ​​of T1 and T2 characterize the spectrum of molecular motion of water molecules.

For bioliquids and tissues of the human body, this spectrum is sharply reduced in intensity at frequencies above a few megahertz and a maximum of hundreds of kilohertz. Therefore, low-pass MRI would be more effective for medical diagnosis,varies considerably when the spectrum of molecular motion in the case of pathological changes, such as cancer.

 

The most powerful magnet for MRI weighs 45 tons

World's most powerful Magnetic Resonance Imaging (MRI), used to study people, is equipped with 45-ton magnet that generates a field with magnetic induction 9.4 T. This exceeds the figure for the outer contour of the largest particle accelerator - the Large Hadron Collider (LHC), work out the 4 tesla. But instead of experiments in fundamental physics, tomography, University of Illinois in Chicago is used to visualize the penetration into the human brain.

With high-powered MRI scientists can measure the concentration of sodium, oxygen consumption and the number of cells in the brain of energy. Together, the three "bio scale" provide a detailed picture of the organ tissue, potentially allowing a notice neurodegenerative disorders long before symptoms appear. There are four such apparatus. Normal scanner generates no more than 3 tesla. A magnet, embedded in a variety of items that are placed on the refrigerator, have a magnetic induction of about 0.05 Tesla. "Without such a magnet, we would not have gone so far - the director of the Center for Magnetic Resonance (Center for Magnetic Resonance Research) at UIC. - It would take years and years to figure out how to overcome barriers in research with common 3-T diagnostic MRI. " Although the new magnet is impressive, it can not be compared with the static magnetic field, obtained in the National Laboratory for High Magnetic Fields (National High Magnetic Field Laboratory), University of Florida (Florida State University) in Talahassi - 45 tesla. In neutron stars - from 1 mT to 100 mT.

ASTRI and Time Medical Inc. (TiMed) announced the breakthrough collaboration on the most advance technology and innovative product in magnetic resonance imaging (MRI) on 17 September, 2008. The live demonstration illustrated its characteristics of low cost, high quality and small size. ASTRI and TiMed R&D team is now applying the technology in athletes' body check so as to enhance their overall training efficiency.

 

Prof. Edward Yang, Chief Executive Officer of ASTRI stated, "Nowadays, clinical industry commonly makes use of MRI Technology. Compared with other technology such as Ultrasound, MRI is still too expensive. Therefore, ASTRI and TiMed jointly developed a new MRI system, which not only can reduce the production cost of the device, but also achieve a high quality imaging effect."

 

A direct modulated optical link for MRI RF receive coil interconnection

Optical glass fiber is a promising alternative to traditional coaxial cables for MRI RF receive coil interconnection to avoid any crosstalk and electromagnetic interference between multiple channels. A direct modulated optical link is proposed for MRI coil interconnection in this paper. The link performances of power gain, frequency response and dynamic range are measured. Phantom and in vivo human head images have been demonstrated by the connection of this direct modulated optical link to a head coil on a 0.3 T MRI scanner for the first time. Comparable image qualities to coaxial cable link verify the feasibility of using the optical link for imaging with minor modification on the existing scanners. This optical link could also be easily extended for multi-channel array interconnections at high field of 1.5 T.
