<p>A new technique called volumetric hatching visualizes medical data using pen-and-ink illustrations. Pen-and-ink illustrations are widely used to portray anatomy in, for example, medical textbooks. Generating such images from medical data provides an alternative form of medical visualization, offering better medical understanding. While most existing pen-and-ink illustration techniques work on surface models, the distinctive feature of this work is that the hatching is based directly on volume data. As with conventional volume rendering, data beneath the surface of the objects influences the results of volumetric hatching, and it is thus suitable for subjects not well represented by a few isosurfaces.</p>
