In this note, we employ a conformal mapping technique for flattening branching tubular structures for visualization of MRA and CT volumetric vessel imagery. This may be used for the study of possible vessel pathology (cerebral embolism, cerebral thrombosis, or lung nodules near vessels). Our method is based on a discretization of the Laplace-Beltrami operator to flatten a surface onto a planar polygonal region in an angle-preserving manner.
