摘要：
The algorithm for obtaining high-quality structural images in endoscopic optical coherence tomography with a reduced level of speckle noise is described. The key features of the developed algorithm are the multilevel filtering and morphological digital processing of structural images. Structural images of soft biological tissues in vivo and tissue-like phantoms are shown. The suggested algorithm can be used to improve quality of structural images not only in optical methods of visualization and non-destructive testing, but also in ultrasonic ones.
