Patent ID: 8724877

Claim:
A mirror image suppression method, adapted to an optical coherence tomography (OCT) system, the method comprising: (a) obtaining a tomography image of an object to be tested by using the OCT system; (b) calculating one real image signal obtained from an n th specific-mode scan for a specific pixel of the tomography image based on image signals obtained from an (n−1) th and the n th specific-mode scans; (c) obtaining one real image signal of each of a plurality of pixels in the tomography image based on the calculation in the step of first calculating the one real image signal; (d) calculating one real image signal obtained from the n th specific-mode scan for the specific pixel at the same position, based on image signals obtained from the n th and an (n+1) th specific-mode scans; (e) arithmetically averaging the real image signals of the pixel at the same position obtained in the step of first calculating the one real image signal and the step of second calculating the one real image signal; and (f) arithmetically averaging the real image signal of each of the pixels in the tomography image based on the calculation in the step of arithmetically averaging the real image signals of the pixel at the same position.
