Abstract
C-arms can be used in surgery to acquire rotational cone-beam data, which can be used to obtain three-dimensional reconstructions of anatomy. In many scenarios, there is insufficient space or capability to obtain the large angular rotations required to reconstruct artifact-free anatomy. Projection data can also suffer from truncation, which causes additional artifacts in three-dimensional reconstruction. In this paper we present a method that compensates for truncation using prior information from computed tomography and provides accurate reconstruction in the mid-plane under certain conditions.
