摘要: The slice thickness of tomograms an X-ray CT apparatus is to be kept as constant practicable within xy plane. In projected data before three-dimensional back-projection, after convolving row-directional filter detector whose coefficient adjusted channel by channel, back-projection performed achieve image reconstruction thereby control the according distance from center controlled keep it independent that regulate picture quality tomograms. Further, relative density distances on plane or projection creating virtual improve
