简介 PROBLEM TO BE SOLVED : To provide a method for reconstructing a three dimensional image based on a limited field of view and at least one corrective parameter. SOLUTION : A system of X-ray imaging includes an X-ray emitter that projects X-rays. An X-ray receiver receives X-rays from the X-ray emitter to produce a plurality of projection images. A filter with at least one filter leaf absorbs at least a portion of the X-rays from the X-ray emitter to define a limited field of view within a full field of view with the X-rays being attenuated in at least one attenuated portion of the full field of view. A processor reconstructs a three dimensional image based upon the projection images of the full field of view. The limited field view is located within the reconstructed three dimensional image. At least one corrective parameter is determined from the reconstructed three dimensional image. SELECTED DRAWING : None COPYRIGHT : (C)2016, JPO&INPIT
