Calculation of Parameters of Saccular Aneurysm

Abstract

The methodology of modelling 3D aneurysm image points was suggested in the article. The ellipsoid was used for the modelling of human‘s saccular aneurysm. The spread of aneurysm image points was analysed with respect to the chosen ellipsoid surface as well as the deviation of the calculated volume. The position and the size of the aneurysm in human‘s brain were described by the mass center point, the directions and the length of the ellipsoid axes as well as the ellipsoid volume. The mass center point was calculated as the mass center of aneurysm image points. The end points of the axes were found by choosing two furthest points of the aneurysm. The volume was calculated using the axes lengths of the ellipsoid. 3D aneurysm model at four different resolutions was used in this research. All the modelling stages were realised using programming language C. Ill. 5, bibl. 7 (in English; summaries in English, Russian and Lithuanian).
