Abstract
In neurosciences, 3D renderings of the human brain cortex based on MR tomographical measurements are often used to study cortical structures, their similarity or variability, or to depict surface distribution of a given physical quantity. We have developed a method for producing maps of the human cortex depicting the complete brain surface in one view. The mapping is based on casting rays normal to the skin surface of the head. The projection surface is then remapped to the plane. An analytical model of the head consisting of four Bezier patches is used for generating the normal rays. The contribution describes the structure of the model and its computation, the projection geometry of the mapping, and the details of the rendering phase. Examples of possible applications of the method are presented.
