Description

A method for the fast calculation of the X-ray transform from the radial derivative of the 3D Radon transform is presented. The introduced technique calculates the x-ray transformation of a given volume data set with an expected computational complexity of the order O(N2logN), instead of O(N3) for ray-tracing. The algorithm is capable of speeding up several applications such as intraoperative 2D/3D registration and tracking or virtual CT diagnosis. (author)
