Three-dimensional vascular reconstruction from projections: a theoretical review

The three-dimensional reconstruction of vascular networks from X-ray projection images is reviewed in analogy to general three-dimensional computed tomography. Intrinsic vascular bed properties (connectivity, density (spareness), lumen dimensions, radio-opaque contrast uniformity, etc.) suggest a general data representation, provide a basis for the algorithmic nature of reconstruction, and can be used to predict tradeoffs between reconstruction accuracy, number of views, and view orientation.<<ETX>>
