  abstract =   "Traditional volume visualization techniques sometimes
               provide incomplete clinical information needed for
               applications in medical visualization. In the area of
               vascular visualization important features such as the lumen
               of a diseased vessel segment may not be visible. One way to
               display vascular structures for diagnostic purposes is to
               generate longitudinal cross-sections in order to show their
               lumen, wall, and surrounding tissue in a curved plane.
               Curved planar reformation (CPR) has proven to be an
               acceptable practical solution. We discuss four different
               methods to generate CPR images from single vessel segments:
               Projected CPR, stretched CPR, straightened CPR, and helical
               CPR. Furthermore we investigate three different methods for
               displaying vascular trees: Multi-path projected CPR,
               multi-path stretched CPR, and untangled CPR. The principle
               concept of each method is discussed and detailed information
               for the realization is given.                  In addition
               the properties, advantages and disadvantages of each method
               are summarized.",
