Betatron-based Digital X-ray Imaging Image System Design And Implementation

X-ray imaging technology from the earliest film imaging development to the current digital imaging,is widely used in medical,security,industrial flaw detection,non-destructive testing and other fields.Most X-ray imaging systems on the market are complex in structure,difficult in operation,expensive in cost,and the ray source is a low-dose X-ray machine,which cannot penetrate objects of greater thickness,limiting the detection range.Therefore,the development of a digital X-ray imaging system with simple structure,high penetration power and high imaging quality has a broad application prospect.To address the above problems,this paper develops a digital X-ray imaging system with a small electron induction gas pedal(Betatron)as the ray source by realizing the need for fine penetration of small and medium-sized inspected samples.In this paper,the following studies are done.(1)Analysis of X-ray and imaging principles,and design of a high-precision X-ray imaging system solution with a Betatron,a high-precision mobile stand,an imaging line array detector,and Betatron imaging software.(2)The correction algorithm was studied for the non-uniformity of X-ray imaging,and the algorithm was improved,and the effectiveness of the improved algorithm was verified;the noise problem in the X-ray imaging process was analyzed,and the related noise reduction algorithm was studied,and the effectiveness was verified after the optimization of the algorithm.(3)The enhancement scheme is given for the acquisition image is dark and the contrast is not high,and the technical scheme of dual-energy imaging is proposed to carry out high-and low-energy scanning imaging for the complex structure of the detected objects separately,and the SIFT algorithm is cited for alignment fusion,and the applicability of the SIFT algorithm is verified.(4)The imaging system software is written in Py Charm environment based on Python,which integrates image acquisition,image processing and image management functions and can effectively implement the algorithms of this topic and present them within the software with a simple,clear and efficient interface.Through the integrated solution of this paper,the fine fluoroscopy of the examined sample was tested using a small cross placed by iron pieces,and the test showed that the method of this paper can clearly identify the internal structure of the object,which proves the effectiveness and usability of the method of this paper and meets the teaching and practical research work needs of the user unit.
