METHOD OF IMPROVING QUALITY OF STRUCTURAL IMAGE OF BIOLOGICAL OBJECT IN OPTICAL COHERENCE TOMOGRAPHY Russian patent published in 2014 - IPC G06T9/00 H04N5/325 A61B8/13 

FIELD: physics.

SUBSTANCE: disclosed is a method of obtaining a structural image of a biological object in optical coherence tomography. The method includes breaking down a source colour vide frame into non-overlapping spatial blocks consisting of more than one pixel. A structural image is obtained via small-angle raster scanning in the arm of an optical coherence tomography sample. The obtained image with a size of P_iskh bytes is broken down into non-overlapping spatial blocks only on columns; adjacent column blocks are averaged pixel by pixel to form a new image with a size of P_stl bytes; the new image is broken down into non-overlapping spatial blocks only on rows; adjacent row blocks are averaged pixel by pixel to form a resultant image with a size of P_res bytes, and the averaging process is controlled based on an exponential relationship P_stl from the number of averaging column blocks U_stl and P_res from the number of averaging row blocks - U_str.

EFFECT: high quality of the structural image of a biological object in optical coherence tomography.
