A research team led by SPbPU professor Vladimir Ivanov, in partnership with neurosurgeons from a specialized hospital in Chennai (India), has successfully tested an improved version of a surgical navigation system based on artificial intelligence and augmented reality. The development allows detailed 3D holograms of brain structures integrated with MRI data to be projected onto the surgical field in real time, which increases the accuracy of interventions and reduces intraoperative risks.
Surgical navigation is the gold standard in modern neurosurgery. However, traditional systems have limitations, requiring the surgeon to constantly shift his gaze from the surgical field to a separate monitor. Augmented reality (AR) and artificial intelligence (AI) technologies are designed to solve this problem by integrating virtual 3D models of anatomical structures directly into the surgeon’s field of view.
One of such promising developments is the Medgital Vision software and hardware complex, created by the research group of Professor Vladimir Ivanov from the Higher School of Theoretical Mechanics and Mathematical Physics of SPbPU.
The Medgital Vision system is a complex that combines algorithms of computer vision, machine learning and augmented reality.
3D reconstruction. Based on MRI/CT data, AI algorithms create highly accurate 3D models of the surgical area, in particular, complex brain structures. Holographic projection. The model in the form of an interactive hologram is projected directly onto the surgical field through an AR headset or a specialized display, providing the surgeon with “X-ray” vision. Intraoperative navigation. The system tracks the position of surgical instruments in real time and combines them with a virtual hologram, ensuring the highest navigation accuracy.
The updated version of the system was tested by the leading developer Ildar Mamaev at a specialized hospital. At the request of Indian colleagues, the AI algorithms were modified for even more detailed visualization of specific areas of the brain. The very first operation performed using the updated system confirmed its clinical effectiveness and stable operation in the conditions of a real surgical process.
The success in India continues a series of international adoptions of the technology.
2023 — the first operations using the system were performed in medical centers in Turkey and Belarus. 2024 — the development received top awards at prestigious international competitions HICOOL (China) and ITECH (China). 2025-2026 — it is planned to implement the system in clinics in Mexico and Ecuador, as well as to open a full-fledged representative office in India.
The head of the Committee for Industrial Policy, Innovation and Trade of St. Petersburg, Alexander Sitov, noted: St. Petersburg has enormous potential in creating artificial intelligence technologies. We are among the leaders in the country in the field of AI development. The city helps developers determine the maturity level of their technologies and promote them to international markets, which is clearly demonstrated by the success of the Medgital Vision project.
Professor Vladimir Ivanov emphasized: Entering the international arena is not only a commercial task for us, but also an important stage in validating the technology. Each new implementation in the world's leading clinic provides invaluable data for further improvement of artificial intelligence algorithms and increasing the accuracy of the system.
Successful testing of the Medgital Vision system in India confirms its competitiveness in the global medical equipment market. The development of St. Petersburg scientists makes a significant contribution to the development of digital surgery, allowing to increase safety and reduce the invasiveness of complex neurosurgical operations. Further international expansion and collection of clinical data will contribute to the evolution of the system towards full automation of surgical planning.
