摘要: We describe a technique for 4D-reconstruction of coronary arteries from sequence monoplane X-ray angiograms. An initial 3D model centerlines is reconstructed two appropriate views. A 3D-2D registration framework formulated in which the deforms space to best fit given The motion hierarchical and includes rigid, affine B-spline transformations. guided by sum energy terms measures goodness mapping constrains deformation model. method tested on three sequences patient data, each containing 248 frames. time one frame varies between four minutes.
