MIEM HSE Students Develop MRI Smart Blanket
The smart blanket was presented at Sirius Scientific and Technological University in Sochi and awarded first place at a physical sciences hackathon. Over the course of one day, 15 student teams had to choose a topic, study the market, develop a concept, and present a prototype of their electronic device.
At the hackathon, the inter-university team representing HSE University, the Moscow Institute of Physics and Technology (MIPT), and Bauman Moscow State Technical University, decided to improve the way in which MRI machines work. According to the developers, the existing technology has major disadvantages. Firstly, MRI devices rely on receiving coils that are specific to each part of the body, and in order to move the device, you have to change the connection diagram of the receivers. Secondly, due to the rigid frame design, they do not fit patients’ bodies snugly, and obtaining a clear picture requires a lot of time.

In simple terms, an MRI device consists of three types of coils, two of which – radio frequency and gradient – are external. The rest, the receivers, are located in various receiving points. They number anywhere from 40 to 100, and, depending on what part of the body is currently being scanned, a certain set is used. Moreover, the device has only eight channels, or, at most, 16. This feature requires the doctor to change the receivers before each new patient — after all, one patient might need a scan of his hand, another might need a scan of her head, another might need one of his chest, and so on.
Moreover, the MRI machine cannot be turned off; it must always be on. And additional devices can’t be used, since the channels are patented by the manufacturer. In light of these issues, the team came up with the idea of a ‘smart blanket’ that doesn’t need to be hooked up directly to an MRI machine. Instead, a doctor simply covers the area of a patient’s body in question, and, due to its flexible fit, receives a high-quality image. A single-channel transmitter is suitable for any part of the human body and is autonomous from the rest of the device.
‘We delved into the problem as deeply as possible and chose several cheap and ready-made technologies: printing soft coils, transferring data through an external coil, a low-current verification system to more accurately determine the area being scanned, and a wireless power system supplied by the energy of the MRI,’ says MIEM student Maria Loseva. ‘As a team member, I answered tricky questions from the jury, and our team members from MIPT searched for information, selected relevant research and technology on the topic, and justified the device’s implementation. Valeria Gress from Bauman conducted a competitive analysis and drew up the prospects for the development of the project, and Darya, our team leader, combined all of our work into a single whole and presented the project at the defense.’
The hackathon was held as part of the Big Challenges Summit, co-organized by the Talent and Success Foundation and the recently opened Sirius University of Science and Technology. Every year, students, graduate students, researchers, and representatives of companies and research centres attend the summit to discuss current scientific research and conduct open discussions with leading scientists and company leaders.
This year 1500 participants from 100 countries took part in the Junction International Hackathon. A team of second-year students of the HSE Faculty of Computer Science (Timofey Smirnov, Igor Zverev, Ainur Nuriev and Aldar Danilov) led by Maxim Dyakov (first-year student of the programme in E-Business) presented a smart lighting project.
HSE University has recently hosted an SAS Data Hack Platypus data analysis hackathon, where teams competed to solve a case problem provided by the online hypermarket, Utkonos (or, in English, ‘Platypus’).The top five finalists received devices from partner companies as gifts.
Over the last several years, hackathons have gone from being competitions for geeks to a must-have line on the resume of almost any job seeker. HSE University students are participating in these kinds of competitions more and more often, and they sometimes even organize their own. Alexander Popovkin, head of HSE’s Hacking Club, spoke with HSE News Service about the benefits and drawbacks of hackathons.
Approximately 200 teams (764 participants) gathered at Hack.Moscow v3.0, an annual hackathon that was held for the third year in a row from October 25 to 27. The winners shared 1 million roubles from sponsors and had the opportunity to earn preferential admission to master's programmes at HSE, the hackathon’s partner university.
HSE students participated in Creation Lab, an annual international business hackathon, which is organized as part of the World Business Dialogue in Cologne. The forum’s partner educational, power and retail businesses will implement the best of the suggested solutions in their operations.
In late October, students from the HSE School of Business Informatics organised the second Major League Hacking (MLH) hackathon hosted in Moscow. The participants of the event, which include students and alumni of Russian and foreign universities, developed IT solutions for Russian companies.
HSE students recently attended Creation Lab, an international business hackathon, where they presented their projects for the international partner companies. The hackathon was organized as part of the World Business Dialogue forum.
The MacDacHack team, which includes HSE students and one alumna, recently won a Big Data hackathon held by McKinsey and Gett.
Major League Hacking (MLH) holds its events around the world, but this year is the first time MLH Local Hack Day is taking place in Russia thanks to the initiative of students from the Higher School of Economics. Participants of the hackathon developed IT solutions for some of Russia’s largest companies.
HSE students from the Faculty of Computer Science and the Institute of Education have taken part in the ‘Put Together Your 2035 University’ hackaton. The theme of the hackaton was concerned with developing and designing AI solutions (with the use of machine learning) in education. HSE students took third place and made it through to the finals!
