Systems and methods for improving penetration of radiographic scanners

Abstract

Systems and methods are used to increase the penetration and reduce the exclusion zone of radiographic systems. An X-ray detection method irradiates an object with X-ray fanlets including vertically moving fan beams, each fanlet having an angular range smaller than the angular coverage of the object. The fanlets are produced by modulating an X-ray beam, synchronizing the X-ray beam and the fanlets, detecting the fanlets irradiating the object, collecting image slices from the detector array corresponding to a complete scan cycle of the fanlets, and processing the image slices collected for combining into a composite image.

[0001] Related references [0002] This specification relies on the priority of U.S. Patent Provisional Application No. 62 / 362,585, filed July 14, 2016, entitled "Systems and Methods for Improving Penetration of Radiographic Scanners." [0003] The entire contents of the aforementioned applications are hereby incorporated by reference. technical field [0004] This specification relates to radiation imaging systems. More specifically, the present specification relates to a method of increasing the penetration and reducing the exclusion zone of a radiology imaging system. Background technique [0005] X-ray imaging is one of the most common methods used to detect contraband in cargo. However, during the inspection of large containers, due to insufficient penetration of radiation, conventional X-ray systems have in common the generation of images with dark areas. These dark areas may indicate the presence of hazardous materials; however, these dark areas give little informa...
