Measurement of the MTF of a Cone-Beam Breast Computed Tomography laboratory scanner.

, 2009
In the framework of the realization of dedicated Cone-Beam Breast Computed Tomography (CBBCT) apparatus we report the MTF characterization of our prototype having the best performance in terms of detector pixel size and X ray focal spot than any other ...

Parallel Implementation of the Katsevich's FBP Algorithm

International Journal of Biomedical Imaging, 2006
For spiral cone-beam CT, parallel computing is an effective approach to resolving the problem of heavy computation burden. It is well known that the major computation time is spent in the backprojection step for either filtered-backprojection (FBP) or ...

Exact Image Reconstruction in Cone Beam 3D CT

, 1995
In cone beam CT, the measured x-ray data represent 1D line integrals through the 3D object. The object can be reconstructed via 3D inverse Radon transformation from the 2D planar integrals, or Radon transform, of the object if the latter can be ...

Spiral Cone-beam CT - Successes with Spiral Scans

, 2014
X-ray computed tomography (CT) is instrumental in medicine, industry and homeland security, which depicts internal structures of an object from its shadows projected in a fan-beam or cone-beam from an x-ray source along a appropriate trajectory.
