In some industrial CT applications, the inspected object is invisible or unknown. It is difficult to always move the object in a uniform speed through the rotational gantry composed with an X-ray source and a detector, such as seismic and oil exploration and so on. In this paper, we prove a generalized backprojection-filtration(BPF) formula within standard helix cone beam CT to get the sufficient...
In this paper, we propose a reconstruction formula of the exponential Radon transform with 180° data and two iterative schemes in practical implementation.
The local reconstruction from samples is one of most desirable properties for many applications in signal processing. Local sampling is practically useful since we need only to consider a signal on a bounded interval and computer can only process only finite samples. However, the local sampling and reconstruction problem has not been given as much attention. Most of known results concern global sampling...
