Cone-Beam Composite-Circling Scan and Exact Image Reconstruction for a Quasi-Short Object
Here we propose a cone-beam composite-circling mode to solve the quasi-short object problem, which is to reconstruct a short portion of a long object from longitudinally truncated cone-beam data involving the short object. ...
Exact Interior Reconstruction with Cone-Beam CT
Using the backprojection filtration (BPF) and filtered backprojection (FBP) approaches, respectively, we prove that with cone-beam CT the interior problem can be exactly solved by analytic continuation. The prior knowledge ...
Exact Interior Reconstruction from Truncated Limited-Angle Projection Data
Using filtered backprojection (FBP) and an analytic continuation approach, we prove that exact interior reconstruction is possible and unique from truncated limited-angle projection data, if we assume a prior knowledge on ...
