Description
Technical field
The utility model relates to a kind of x-ray imaging technology, comprises back scattering imaging and transmission imaging, and relates in particular to a kind of X ray rotating disc type flying spot that opens circuit and form device.
Background technology
At present, in the prior art, the method that is used for the point by point scanning of x-ray imaging mainly contains three kinds, below, these three kinds of scan methods are done simple introduction.
Please refer to Fig. 1, Fig. 1 is the apparatus structure synoptic diagram of prior art x-ray imaging point by point scanning, among Fig. 1, radiographic source 2 with about cut wheel and 1 link to each other; Cut wheel 1 upper edge radial direction about said and evenly be furnished with collimating aperture 8, radiographic source fixing support rack 6 links to each other with said radiographic source 2, plays a supportive role; Motor 7 is positioned at the below of cutting wheel 1 about said, major impetus is provided, two backward scattering detectors 5; Be placed in and cut the both sides of wheel 1 about said, launch and form form of a stroke or a combination of strokes beams 9 in the ray in the center of circle along collimating aperture 8 and penetrate, be mapped on the seized object 3 and form circular spot; Be flying spot, the opposite side of seized object 3 is placed 4 pairs of scanning results of a transmission detectors and is observed.This method is simple and practical, but on the emission covering of the fan of X ray, exists the uneven problem of X ray intensity, can cause the transmitted intensity of analyzing spot inconsistent, thereby to having influence on the accuracy of scanning result; In addition, the Circularhole diameter in this device is very little, and processing is difficulty relatively.
Please refer to Fig. 2, Fig. 2 is the apparatus structure synoptic diagram of prior art backscattering formula X-ray scanning appearance, and backscattering formula X-ray scanning appearance mainly comprises x-ray source, flying spot beam generator, fan-shaped collimating apparatus 12, detector 18 and sensor 27.X-ray source is made up of X-ray tube 11, high-voltage power supply 15 and cable 26, and they and fan-shaped collimating apparatus 12 all are placed in the drum 19.On the same circumference of drum 19, be provided with 1-4 square or circular aperture 20, generally between the 1-5 millimeter, the stereotype that is inlaid with 3 millimeter in the inboard of drum is as screen layer for the size of aperture.Its principle of work is: drum 19 is around X-ray tube 11; Fan-shaped collimating apparatus 12 moves in a circle; Aperture 20 is also done same motion and is produced bar-shaped beam 21, and bar-shaped beam is beaten at drum and done on the seized object 14 of linear relative movement, on seized object 14, forms sweep trace 13; The reflection back forms backscattering ray 16, injects special-purpose detector 18.Circularhole diameter in this device is still very little, and processing is difficulty relatively, and fan-shaped collimating apparatus in inside that this device is many is in addition drawn a snake and add feet to it on the contrary, makes an unnecessary move.
