摘要：

In this paper, we present a practical Feldkam-plike algorithm for flat-panel cone-beam reconstruction from a planar source trajectory with varying radius. Along with the reconstruction, our algorithm simultaneously recovers the shape of the field-of-view, which can be of complex structure in variable-radius geometries. Numerical results of our algorithm are presented for a short-scan rectangular acquisition geometry as well a full-scan flower-shape geometry. Evaluation was carried out using simulated data of the FORBILD head phantom.
