Paper Abstract

A method is presented to automatically determine the three-dimensional geometry of a stationary vessel tree from orthogonal biplanar digital angiographic image sequences, without a priori knowledge or user interaction. Vessels are identified unambiguously by their position in each projection and by comparison of time-density curves. Single-plane angiographic sequences are used to illustrate the technique, simulating a single slice of three-dimensional data. Projections are taken in each direction, yielding one row and one column of data which are used to reconstruct the vessel geometry. It is demonstrated that overlapping vascular regions can be resolved by temporal processing of angiographic image sequences, although high-quality reconstruction has not yet been achieved.
