RECONSTRUCTION METHOD OF THE INTACT SURFACE OF SURGICAL ACCESSES.

The developed construction method of the intact surface of surgical accesses and its visualization for the problems of planning stereotactic interventions on the human brain is described in the paper. This representation allows to combine the surgery risk estimates with the patient's skull geometry, thereby ensuring a reasonable choice of surgical access by surgeon-specialist. The method consists of the reconstruction of the object, on which the surgeryrisk data is further directly applied. A distinctive feature of the reconstruction method, described in the paper is that the construction of a geometric object is made based on surgical accesses. Also, due to using connectivity of vertices obtained during reconstruction, filtration of the resulting geometry without the need for additional transformations is possible. The research results can be used to create the neurosurgery planning system that will allow to reduce the mortality rate of the human brain surgeries. [ABSTRACT FROM AUTHOR]
