Embodiment Construction
[0014] Below in conjunction with accompanying drawing, the present invention will be further described:
[0015] The anti-scatter X-ray scanner provided by the present invention mainly includes an X-ray source, a flying spot beam generator 9 , a sector collimator 2 , a detector 8 and a sensor 17 . The X-ray source consists of an X-ray tube 1, a high-voltage power supply 15 and a cable 16, which are placed in the drum 9 together with the fan-shaped collimator 2. There are 1 to 4 square or circular small holes 10 on the same circumference of the drum 9. The size of the small holes is generally between 1 and 5 mm, and a lead plate of about 3 mm is inlaid on the inside of the drum as a shield. Floor. Its working principle is: the cylinder 9 winds around the X-ray tube 1, the fan-shaped collimator 2 performs a circular motion, and the small hole 10 also performs the same motion to generate a rod-shaped beam 11, and the rod-shaped beam hits the cylinder that is relatively linearly ...
