摘要
Equipment and methods are presented for rearranging divergent beam derived data into parallel data to enable decreasing the number of preprocessing computations and improving the quality of the resulting tomograph. The equipment and method comprise means and steps which vary the spacing of at least portions of the resulting parallel projections, so that when the parallel projections with varied spacings are combined with the parallel projections that have not had their spacing varied, the cupping artifacts normally present when using projections obtained from rearranging are cancelled.
