Computerized tomography using a modified orthogonal tangent correction algorithm
A modified orthogonal tangent correction algorithm is presented for computerized tomography. The algorithm uses four X-ray scans spaced 45° apart, to reconstruct a transverse axial image. The reconstruction procedure is interative in which image matrix elements are corrected by alternately matching...

| description | A modified orthogonal tangent correction algorithm is presented for computerized tomography. The algorithm uses four X-ray scans spaced 45° apart, to reconstruct a transverse axial image. The reconstruction procedure is interative in which image matrix elements are corrected by alternately matching the two sets of orthogonal scan data. The algorithm has been applied to phantom data as well as to video recorded fluoroscopic data. |
