RISA New Algorithm for Multimodal Medical Image Fusion Based on the Surfacelet Transform
Nowadays, medical imaging becomes a common part of everyday clinical practices. Despite enormous progresses, still there is no single modality which can represent all aspects of the human body. For example, CT is suitable to view dense structures...
A quaternionic approach to x-ray transform inversion in R3
A new derivation of the inverse of the x-ray transform is presented based on
quaternion analysis. As pointed out by practitioners, a direct inversion formula
offers more efficient reconstruction algorithms ...
The R3 exponential x-ray transform inversion in quaternion analysis
In this paper, we present a new derivation of the inverse of the exponential x-ray transform in the three dimensions, based on quaternion analysis. An explicit formula is obtained using a set of three-dimensional x-ray ...
Investigation of Ni/epi-SiGe layer stacks annealed by microwave heating
Polarization selective one-way microwave absorber based on composite metamaterial
An Efficient 3D Gradient-Based Algorithm for Medical Image Registration Using Correlation-Coefficient Maximization
Most registration algorithms for medical images may suffer from slow convergence and sensitivity to initialization. In this paper, we propose an efficient gradient-based algorithm for rigid intensity-based registration of medical images. It takes...
Inversion formula for the non-uniformly attenuated x-ray transform for emission imaging in R3 using quaternionic analysis
In this paper, we present a new derivation of the inverse of the non-uniformly
attenuated x-ray transform in three dimensions, based on quaternion analysis.
An explicit formula is obtained using a set of ...
