Abstract:
1. A method for substantially reducing the contribution of dense regions of an object while less dense regions of said object are being processed in a laminography blurring system, said method comprising the steps of: (a) positioning an x-ray source with a moving fan beam on one side of said object; (b) positioning a row of x-ray detectors on the side of said object opposite that of said x-ray source; (c) sequentially emitting a plurality of x-ray fan beams along an x-ray source line and directed through a focused pixel of said object to said row of x-ray detectors; (d) sampling said x-ray detectors once for each of said plurality of fan beams for a total of it samples of intensity I (e) determining the maximum intensity I (f) choosing a parameter P greater than one; (g) retaining only those of said samples I (h) summing said retained samples; and (i) normalizing the resultant sum.
