Title:
X-RAY CT IMAGE RECONSTRUCTION EFFECTIVE FOR BROAD RANGE OF CURVED TRAJECTORY
Document Type and Number:
Japanese Patent JP2008110020
Kind Code:
A
Abstract:
To provide an X-ray CT image reconstruction method effective for a broad range of curved trajectory.
It is assumed that the trajectory of an X-ray source has a plane determined by a slice to be reconstructed and three or more intersections, and the intersections constitute a convex polygon. A precise, effective and simple three-dimensional image reconstruction method is provided for projection data captured on the trajectory.
