Visualization of ventricles of the brain by volume rendering

Preliminary results of applying the advanced three-dimensional visualization techniques of volumetric rendering to represent state-of-the art magnetic resonance images of the ventricular system are reported. Cinematic loops provide the subjective impression of a rotating 3-D object in space, thus enhancing the appreciation of the 3-D structure. Different images were obtained by changing the color/opacity parameters and transparency factors. Only minimal editing was required to obtain the judges. It was not necessary to trace the precise ventricular borders as is usually required in computer graphics approaches. Initial results suggest that volumetric display of magnetic resonance images of the brain can be of value for the assessment of the ventricular system deep with the brain paraenchyma
