Построение структурного изображения биообъекта с использованием растрового усреднения в оптической когерентной томографии

Построение структурного изображения биообъекта с использованием растрового усреднения в оптической когерентной томографии

Abstract

Предлагается усовершенствованный алгоритм построения структурного изображения биообъекта для оптической когерентной томографии, позволяющий увеличить глубину когерентного зондирования и получить изображение более высокого качества. К предлагаемым усовершенствованиям относится: использование гальваносканера вместо скани рующего предметного столика, растровое усреднение, собирающее несколько соседних пикселей в один и сложная многоуровневая фильтрация. Алгоритм включает в себя частотную фильтрацию полосовым фильтром Баттерворта 3-го порядка, амплитудную пороговую фильтрацию и графическую фильтрацию на основе медианного фильтра

Advanced algorithm of Optical Coherence Tomography structural image reconstruction of a biological object is proposed. It allows increasing coherence probing depth and obtaining image of higher quality. The proposed advantages are: application of Galvanoscanner instead of scanning stage, raster averaging which collects several adjacent pixels in one and complex multilevel filtering. The algorithm includes 3-d order band pass Butterworth frequency filtering, amplitude step filtration and graphical filtration using median filter.
