Embodiment Construction
[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0044] Such as Figure 9 A jumper flying spot scanning device for an X-ray backscatter imaging system is shown, including a ray source 16 located in the X-ray machine 1, and an incident collimator connecting the X-ray machine 1 and the scanner outer cylinder 4 2. The scanning drum 7 fixed in the outer cylinder 4 of the scanner through the rotating shafts 8 at both ends, and the exit collimator 3 connected with the outer drum 4 of the scanner, is characterized in that: the scanning drum 7 A number of discontinuous incident slit sections 11 and exit slit sections 12 are engraved on the side wall, which can be formed by one incident slit section 11 and one exit slit section 12 at any time when the scanning drum 7 rotates. The only scanning collimation hole. The outer cylinder 4 of the scanner is a hollow steel cylinder with uniform wall thicknes...
