技術摘要 / Our Technology:
一種鏡像消除方法,適用於一光學同調斷層成像系統。所述鏡像消除方法包括:(a)利用光學同調斷層成像系統,取得一待測物的斷層影像;(b)針對特定畫素,利用第n-1個及第n個特定掃瞄模式所得之影像訊號,計算出第n個特定掃瞄模式所得之實像訊號;(c)根據步驟(b)之計算方式,針對斷層影像中的多個畫素,取得各畫素的實像訊號;(d)根據步驟(c)所得之各畫素的實像訊號,重建該斷層影像,以消除斷層影像的鏡像訊號。

A mirror image suppression method adapted to an optical coherence tomography (OCT) system is provided. The mirror image suppression method includes the following steps: obtaining a tomography image of an object to be tested by using the OCT system; calculating one real image signal obtained from an nth specific-mode scan for a specific pixel of the tomography image based on image signals obtained from an (n−1)th and the nth specific-mode scans; obtaining one real image signal of each of a plurality of pixels in the tomography image based on the calculation in the step of calculating the one real image signal; and reconstructing the tomography image based on the real image signal of each of the pixels obtained in the step of obtaining the one real image signal to suppress mirror image signals of the tomography image.
