How to trick computer scanner?

Skeptics who doubt the effectiveness of computed scanner of the brain to identify perjury, got a new argument in its favor. It seems that you can really outsmart tomography.

In a related study conducted at Harvard Medical School, involved 26 volunteers. A brain scan was carried out at a time when the subjects watched the screen, where the six calendar dates alternated every half second. It was necessary to push the buttons "Yes" or "no" in cases where the number or may not coincide with the date of their own birth. In the first part of the experiment there was no correspondence, and study participants with a pure heart pressed the button "No". But the second part of one of the dates coincided with the date of birth, but the subjects were asked to lie still and still press "No".

Professor Giorgio Ganis (Giorgio Ganis), Head of the Laboratory of radiology at Harvard, found that when subjects were lying, brain scans showed increased activity in their frontal lobes (in the ventrolateral and medial parts of the region in pre-frontal cortex).

Then the experiment participants learned simple way to outwit the machine: they were slightly moving the index and middle fingers on his left arm and left leg toe whenever there are three dates that had no value for the experiment. This trick has led to the focus on the dates which the subject was not easy to outwit the MRI scanner using simple tricks need to "hide", and false information could hide. A simple trick could reduce the accuracy of lie detection system in 33%, thereby greatly complicating the examination.

How to make a more accurate lie detector? "This is the million dollar question - said Professor Ganis. - You can display information quickly or make the task so complex that people will have no additional resources for the gimmicks. But to solve the problem as such require further research on the subject. "



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!

Nanoparticles with a remote control to help in cancer treatment

Remote-controlled magnetic nanoparticles improve efficiency and reduce the toxicity of chemotherapy.

Our advanced systems for magnetic resonance imaging (MRI), researchers at the Ecole Polytechnique Montreal, working under the direction of Professor SylvainMartel (Sylvain Martel), successfully delivered anticancer drug-loaded nanoparticles in the hepatic artery of rabbit in the affected area of his liver tumor.This experiment demonstrated the ability to remotely control the movement of carrier nanoparticles in vivo. Due to the sighting of drug delivery, this method will significantly improve the treatment of various, especially malignant tumors, as well as reduce the likelihood and severity of side effects.

We discuss the environmental aspects of biomedical MRI scan. Magnetic resonance imaging MRI, which belongs to the most environmentally friendly methods of medical diagnostics, also has its environmental limits. A comparison of MRI images from scanners with high (3-11 T) and low (0.1-0.5 T) magnetic fields. We consider the advantages and disadvantages of scanners with different magnetic fields and analyze the main trends of modern magnetic resonance imaging MRI. It is shown that does not always increase the magnetic field is a positive factor for compliance with environmental conditions and quality of MRI.
