Фильтрация рентгеновских томограмм методом адаптации размера окна фильтра к локальным характеристикам изображения

Фильтрация рентгеновских томограмм методом адаптации размера окна фильтра к локальным характеристикам изображения

Abstract

Предложен алгоритм фильтрации изображений медицинской рентгеновской компьютерной томографии с адаптацией размеров апертуры и метода фильтрации к локальным характеристикам изображения. Алгоритм реализован в виде программного обеспечения и апробирован на проекционных данных томографических изображений. Приведено описание алгоритма и формул, лежащих в его основе. Оценена погрешность, даваемая алгоритмом, приведено сравнение с существующими методами фильтрации.

Keywords

УДК 519.6, УДК 004.9, Филиал в г. Кыштыме, тестовое изображеник, алгоритм фильтрации, погрешность алгоритма
