Collapsed cone convolutionA collapsed cone convolution algorithm was applied to a treatment planning system for the calculation of dose distributions. The distribution of beam fluences was determined using a three-source model by considering the source strengths of the primary beam, the beam scattered...
challenging task, in particular since very few work has been performed in this domain and a multitude of influence factors being relevant. Last, as mentioned above, a computationally efficient prediction algorithm has been developed, which is able to predict the optimization potential of a given geo...

Feldkamp Davis Kress algorithmconvolution and backprojection methodCone-beam tomography is currently being developed for commercial applications wherever two-dimensional X-ray tomography is being used. One popular method for reconstructing a three dimensional image of an object (from cone-beam data), is...

Based on our recently derived exact fan-beam LT formula, here we propose a practical cone-beam LT algorithm for LT reconstruction from local data collected along an arbitrary smooth 3D curve. A key step in our algorithm is to determine an appropriate vector perpendicular to the line connecting ...
In order to compensate for the error resulting from image segmentation and the unrealistic hypothesis of the analytic algorithm, one iterative algorithm was proposed to find the optimal parameters around the initial estimation. Based on the finding that the error at the analytic step makes ...
Reconstructions were made using a modified Feldkamp filtered backprojection algorithm and were registered and compared for consistency. Inconsistent regions were examined with respect to surface orientation and planar extent. In addition, a section of human vertebra was similarly imaged. 3D Fourier ...
