Abstract

CT scanners have a certain scan-field-of-view defined by the fan-angle of the system. According to an exemplary embodiment of the present invention, object points outside the scan-field-of-view may be reconstructed on the basis of a system of linear equations which may be solved iteratively and with reasonable effort. Therefore, explicit regularization techniques may be applied to recover the unknown object function.
