摘要

Summary the method for removal of artifacts from a field generator in 3D is a 3D rotational scan.System for removal of artifacts from a field generator in 3D is a 3D rotational scan computer program product, and method.System and program product are provided for removal of artifacts from a field generator in a 3D rotational scan.The method comprises: in the preoperative, characterize the artifacts of the field generator on a series of positions of rotation of a source of X-rays and a detector; intraoperative period.Determining the position of the generator field in relation to the X-ray source and detector; and removing the artifacts characterized in preoperative to the relative position determined from the generator DIn an X-ray and field current.
