Novosibirsk State Technical University Student Conducts Research to Detect Brain Tumors and Predict Patient’s Life Span

According to the Russian Federation Ministry of Health, the mortality rate from cancer in Russia is currently more than 200 people per 100 thousand. Brain tumors are found in 65–80% of those who die from oncology. Therefore, diagnosing and monitoring the dynamics of neuro-oncological diseases in patients with primary and secondary brain tumors is extremely important. Early detection of neoplasms significantly improves the effectiveness of targeted therapy (surgical, radiation, chemotherapy, and immunological).

For his final thesis, Maxim Kochanov, a student at the NSU Mechanics and Mathematics Department, considered two problems. The first was semantic segmentation of brain tumors on MRI images and the second predicting the time interval of patients’ lives based on images of segmented brain tumors established solving the first problem. Academic Supervisor Bair Tuchinov, Head of the Laboratory for Streaming Data Analytics and Machine Learning at the Department, was his academic supervisor. To solve these problems, both machine learning and deep learning approaches were used. Data for training machine learning algorithms and neural networks was provided by the international competition Brain Tumor Segmentation Challenge – 2020.

Kochanov described the work. In the course of our thesis work, we developed a prototype for a personalized diagnostics system. An MRI image of the brain is fed to the system and as an output, we receive an image of a specific brain tumor and / or cerebral edema. If there is a tumor on the MRI image and / or swelling, we get the most likely time interval for the patient’s life. This means there is a high applied value in medicine for my thesis.  

Previously, Novosibirsk scientists developed a technology to improve the diagnosis of brain tumors using artificial intelligence.

Discover community volunteering opportunities in Europe through the European Solidarity Corps, international student organisations and your host university. As an international student, you may arrive in a new country which is completely unknown to you. It takes time to get to know your new environment, make friends and to find your way […]

European Higher Education Organization is a public organization carrying out academic, educational and information activities on higher education in Europe.

The EHEO general plan stresses that:

  • Higher education systems require adequate funding and, as an investment in economic growth, public spending in higher education should be protected.
  • The challenges faced by higher education require more flexible governance and funding systems, which balance greater autonomy for education institutions with accountability to stakeholders.

Thus, EHEO plans:

  • improve academic and scientific interaction of universities;
  • protect the interests of universities;
  • interact more closely with public authorities of European countries;
  • popularize European higher education in the world;
  • develop academic mobility;
  • seek funding for European universities.
