An Optimized Spline-Based Registration of a 3D CT to a Set of C-Arm Images
3D CT C-Arm Images
<
2009/9/8
We have developed an algorithm for the rigid-body registration of a CT volume to a set of C-arm images. The algorithm uses a gradient-based iterative minimization of a least-squares measure of dissimi...
Towards a Noninvasive Intracranial Tumor Irradiation Using 3D Optical Imaging and Multimodal Data Registration
3D Optical Imaging Multimodal Data Registration
<
2009/9/7
Conformal radiotherapy (CRT) results in high-precision tumor volume irradiation. In fractioned radiotherapy (FRT), lesions are irradiated in several sessions so that healthy neighbouring tissues are b...

A critical issue in image restoration is the problem of noise removal while keeping the integrity of relevant image information. The method proposed in this paper is a fully automatic 3D blockwise ver...
A Reconstruction Approach for Imaging in 3D Cone Beam Vector Field Tomography
Imaging 3D Cone Beam Vector Field Tomography
<
2009/9/4
3D cone beam vector field tomography (VFT) aims for reconstructing and visualizing the velocity field of a moving fluid by measuring line integrals of projections of the vector field. The data are obt...
