چکیده
تصویربرداری به روش پس ‏پراکنشی مبتنی بر پرتو ایکس توجه روزافزونی را در سراسر جهان به خود جلب کرده و کاربردهای متنوعی از جمله آزمون‏های غیرمخرب، بازرسی امنیتی و کنترل کیفیت در صنعت پیدا کرده است. در مطالعه حاضر، یک دستگاه تصویربرداری پس ‏پراکنشی با باریکه پرتو ایکس مدادی طراحی و ساخته شده است. این اسکنر شامل یک مولد پرتو ایکس صنعتی، دو سوسوزن پلاستیکی، یک چرخ برشگر، یک سیستم جمع‌آوری داده، یک نرم‌افزار پردازش داده و تشکیل تصویر مبتنی بر MATLAB است. چرخ برشگر دوار پرتوهای ایکس مدادی ایجاد کرده کل نمونه را جاروب می ‏نمایند. عملکرد سیستم از طریق مجموعه‏ای از آزمون‏ها با استفاده از قوطی‏های روغن و رنگ (پر و نیمه‏پر) ارزیابی شد. یافته‌ها تأیید می‌کنند که تصویربرداری پس ‏پراکنشی برای جسم‏های با عدد اتمی و چگالی پایین از قبیل چسب، رنگ و روغن بسیار کارا بوده و تصاویر با کیفیتی ارائه می‏ نماید. همچنین، ترکیب داده ‏های هر دو آشکارساز و اعمال یک فیلتر پایین‏گذر بر روی تصاویر سبب بهبود چشم‏گیر کیفیت تصاویر پس‏پراکنشی خواهد شد. مزیت ذاتی دستگاه‏های تصویربرداری پس ‏پراکنشی، اسکن مواد با عدد اتمی پایین (چسب‏ ها، رنگ ‏ها، سیالات مشتق‏ شده از نفت، پلاستیک، پلیمر، مواد منفجره و حتی آلومینیوم) می‏ باشد که نتایج این مطالعه گواهی بر این مدعاست. یافته ‏های این پژوهش نشان دادند که طیف وسیعی از کاربردهای صنعتی برای این دستگاه قابل ترسیم است. فعالیت آتی این مقاله استفاده از روش تقسیم مکانی برای پردازش سیگنال ‏ها و مقایسه آن با الگوریتم تقسیم زمانی (مطالعه حاضر) خواهد بود. همچنین، تصویربرداری از سایر مواد سبک نیز در دستورکار نویسندگان می ‏باشد.

چکیده English

X - ray - based backscattering imaging has attracted increasing attention worldwide and has found a variety of applications in the industry , including non -destructive testing, security inspection , and quality control . In the present study, a backscattering imaging device with a pencil X- ray beam was designed and manufactured . The scanner includes an industrial X - ray generator, two plastic detectors, a chopper wheel, a data collection system, a data processing software, and MATLAB - based image forming . The rotary chopper wheel creates pencil X - rays that sweep the entire sample . The performance of the system was evaluated through a series of tests using oil and paint cans ( full and semi - filled ) . The findings confirm that backscattering imaging is very effective for low atomic and low -density objects such as adhesives, paints, and oils and provides high - quality images . Also , combining the data of both detectors and applying a low - pass filter to the images will significantly improve the quality of the backscatter images . The inherent advantage of backscattering imaging devices is the scanning of materials with low atomic numbers ( adhesives , paints, fluids derived from petroleum, plastics, polymers , explosives, and even aluminum ) , which the results of this study attest to . The findings of this study showed that a wide range of industrial applications can be drawn for this device . The next activity of this paper will be to use the spatial division method to process the signals and compare it with the time division algorithm ( the present study ) . Also , imaging of other light materials is also on the authors' agenda . . . . . . . . . .. . . .
