             abstract = "In Medical Imaging,shell rendering is considered one of the most 
                         efficient and effective methods for volume visualization. It 
                         requires a compact data structure of voxels and uses the voxel 
                         splatting technique for surface and volume rendering. In order to 
                         avoid holes in the rendition, the size of the voxels are usually 
                         made bigger than the size of the pixels for voxel splatting. In 
                         such a case, we have identified a conceptual problem in shell 
                         rendering which affects the correctness and quality of the 
                         renditions. In this paper, we discuss this problem and propose a 
                         solution, which improves image quality without affecting the speed 
                         of the method. The new approach is called E-Shell Rendering 
                         (extended-shell rendering). It requires an extension of the shell 
                         data structure and a variant of the original algorithm. We 
                         illustrate and discuss the results with examples created by 
                         surface and volume rendering.",
