The study relates to the field of automation and information support of the processes of diagnostics and surgical treatment in neurosurgery. On the basis of complex software (BCS), computing and information systems of local corporate information networks of neurosurgical clinics are used, the initial data of standardized diagnostic protocols for clinical and instrumental studies of the brain of neurosurgical patients are formed. The data necessary for modeling are obtained after performing computed tomography (CT) and / or Magnetic Resonance Imaging (MRI), converting an image of the DICOM-PACS (Digital Imaging and Communications in Medicine) format on the network or from standard media (CD-R, CD-RW , USB flash drives, etc.) to build a real-time 3D model of the current state of the operated chronic subdural hematoma of the brain(CSDH), directly during its surgical treatment, based on the current 3D model of the real object of treatment.
