Three-dimensional (3D) image rendering was performed using data from standard CT examinations of the head. In this new method for 3D imaging of the brain surface interactive image segmentation and integral rendering were combined. Interactive segmentation operations meant that 3D images could be obtained within a short period of time. When combined with integral rendering this permits good-quality 3D views, even when generated from standard thick slices, together with visualisation of both the shape and densities of the brain surface. Surface infarctions can be evaluated in terms of their anatomical localisation to gyri and sulci, thus allowing their relationship to functional areas to be better defined. The technique can be an additional, easily obtainable tool, even in routine practice, for a better understanding of neurological signs.

Abstract
Three-dimensional (3D) image rendering was performed using data from standard CT examinations of the head. In this new method for 3D imaging of the brain surface interactive image segmentation and integral rendering were combined. Interactive segmentation operations meant that 3D images could be obtained within a short period of time. When combined with integral rendering this permits good-quality 3D views, even when generated from standard thick slices, together with visualisation of both the shape and densities of the brain surface. Surface infarctions can be evaluated in terms of their anatomical localisation to gyri and sulci, thus allowing their relationship to functional areas to be better defined. The technique can be an additional, easily obtainable tool, even in routine practice, for a better understanding of neurological signs.
