Three-dimensional reconstruction of coronary tree using intravascular ultrasound images

Proposes a new Computer Vision technique to reconstruct the vascular wall in space using a deformable model-based technique and compounding methods, based in biplane angiography and intravascular ultrasound data fusion. It is also proposed a general-purpose three-dimensional guided interpolation method. The three dimensional centerline of the vessel is reconstructed from geometrically corrected biplane angiographies using automatic segmentation methods and snakes. The IVUS image planes are located in the three-dimensional space and correctly oriented. A led interpolation method based on B-surfaces and snakes is used to fill the gaps among image planes.
