Abstract

Двухэнергетическая рентгеновская сканирующая система имеет линейную решетку детекторов с высокоэнергетическими и низкоэнергетическими детекторами. Используют способ обработки сигнала, учитывающий изменения углов, под которыми проходящие рентгеновские лучи падают на детекторы, а также изменение порядка, в котором пропускаемые рентгеновские лучи проходят через высокоэнергетические и низкоэнергетические детекторы. Это обеспечивает как высокое разрешение сгенерированных изображений, так и лучшую эффективность проникновения.
