Background technology
At present, the various channel-type X ray screening machines that use both at home and abroad mainly contain following several types:
First kind; X ray transmission DR (Digital Radiography; The digitizing of X ray is taken a picture) pattern, this pattern (containing monoenergetic and dual intensity) work principle is to combine instrument and testing staff's experience differentiation measured object to be roughly organism, potpourri and inorganics.Though this pattern can detect metal more exactly, light materials contraband goods (like inflammable explosive article) then is difficult to differentiate its classification.
Second kind, the multi-view X ray transmission mode, this pattern can obtain the detection effect that compares better, and still, its subject matter is that image reconstruction algorithm is immature, is difficult to specifically distinguish the light materials contraband goods, and spatial resolution is not high.
The third, single CT pattern, its advantage are to distinguish each ingredient of interior of articles in detail, can solve that article huddle, overlap problem.But because detector array and X-ray production apparatus all need rotate, thereby system is huge and heavy.It costs an arm and a leg, and sweep time is long, particularly can not specifically discern light materials contraband goods type, and the screening machine false alarm rate of existing single CT pattern is up to 20%～30%.
The 4th kind, the pattern of two kinds of combinations of DR and CBS (Compton Backscatter Scanning, light materials detects), its advantage is accurately to detect the metal contraband goods, can specifically identify inflammable explosive article again.But under general configuration condition, the space of CBS rate respectively is not high enough, mainly rebuilds the CBS image for the inflammable explosive article that adapts to solid simultaneously, thereby relatively poor to the measuring ability of liquid contraband goods.
