Abstract
Изобретение относится к рентгенотехнике, в частности, к рентгеновской идентификации инородных предметов и материалов, из которых они изготовлены, и может быть использовано при рентгеновском контроле на пропускных пунктах воздушных, морских портов и предприятий с повышенными мерами безопасности. Техническая задача изобретения - создание способа идентификации материалов, обеспечивающего при низкой дозе облучения человека независимую от инспектора идентификацию и оценку типа материала предмета и его толщины. Способ включает сканирование тела человека карандашным рентгеновским пучком, регистрацию амплитуд сигналов от отраженного и прошедшего рентгеновских излучений, архивацию данных, сравнительный анализ и идентификацию материалов, при которой наряду с визуальной оценкой материала предмета по рентгеновскому изображению используют количественную оценку материала предмета и его толщины с использованием архивированной базы данных сканирования, для чего в подозрительных точках на теле человека вычисляют одновременно величину относительного изменения амплитуды сигнала от отраженного рентгеновского излучения и величину относительного изменения амплитуды сигнала от прошедшего сквозь подозрительный предмет и тело человека рентгеновского излучения, проводят сравнение этих величин с заранее затабулированными значениями относительных изменений амплитуд сигналов для разных материалов, идентифицируют материалы и осуществляют оценку толщины предмета.The invention relates to x-ray technology, in particular, to x-ray identification of foreign objects and materials from which they are made, and can be used for x-ray control at checkpoints of air, sea ports and enterprises with enhanced security measures. The technical problem of the invention is the creation of a method for the identification of materials, providing, at a low dose of human exposure, the identification and evaluation of the type of material of the object and its thickness, independent of the inspector. The method includes scanning the human body with an X-ray pencil, recording amplitudes of signals from reflected and transmitted x-rays, archiving data, comparative analysis and identification of materials, in which, along with a visual assessment of the material of an object from an x-ray image, a quantitative assessment of the material of the object and its thickness using an archived database scan, for which suspicious points on the human body simultaneously calculate the value of relative th change in the signal amplitude of the reflected x-ray radiation and the magnitude of the relative change in amplitude of the signal from transmitted through the suspicious object and the X-ray human body, is carried out to compare these values with predetermined values tabulated relative changes in amplitudes of signals for different materials, the materials are identified and implemented evaluation object thickness.
