PROCEDE DE RECALAGE AUTOMATIQUE D'IMAGES |
摘要 |
Method of automatic registration of two- and three-dimensional angiography images by comparison of a two-dimensional digital subtracted 0angiography image with data on a three-dimensional image reconstructed from rotational angiography sequences, in which a field of distortions in the image is estimated, a conical projection matrix is estimated and an approximation is made of a rigid transformation in space equal to the difference between an initial registration based on the field of distortions and on the conical projection matrix and a perfect registration. |
