Description
本發明相關於一種頻域光學同調斷層掃描系統,特別是相關於一種基於人工智慧技術之全域式頻域光學同調斷層掃描系統。 The invention relates to a frequency domain optical coherence tomography scanning system, in particular to an all-domain frequency domain optical coherence tomography scanning system based on artificial intelligence technology.
光學同調斷層掃描技術(Optical Coherence Tomography,OCT)是一種高分辨率、非接觸、非破壞的生物醫學成像新方法,通過高分辨的探測樣品不同深度層面背向散射回來的光強度,可以得到樣品的深度資訊。此技術能對活體組織的斷層結構和生理功能進行觀察,它具備組織病理分析所需的高分辨力,能發揮病變早期診斷、過程監視和手術引導等臨床功能。 Optical Coherence Tomography (OCT) is a high-resolution, non-contact, non-destructive new biomedical imaging method. By detecting the backscattered light intensity at different depths of the sample with high resolution, the sample can be obtained. in-depth information. This technology can observe the tomographic structure and physiological function of living tissue. It has the high resolution required for histopathological analysis, and can play clinical functions such as early diagnosis of lesions, process monitoring and surgical guidance.
光學同調斷層掃描技術中的頻域光學同調斷層掃描(Fourier Domain Optical Coherence Tomography,FDOCT)之優點為成像速度快。然而,傳統的頻域光學同調斷層掃描於光譜儀所量測頻域上干涉訊號具有餘弦(cosine)函數時,在做反傅利葉轉換所得到時域上的干涉訊號,會讓訊號產生自相關雜訊(Autocorrelation Noise)與鏡像雜訊(Mirror Noise or Conjugate Artifacts)的問題,進而使得量測的樣品訊號模糊不清,對成像品質造成重大的影響而導致使用者難以判讀樣品的真實結構,或是容易產生誤判。在習知技術 中,若欲解決前述之問題,則需要藉由複雜的光學系統、艱難的演算法,甚至需要多次量測來累積樣品的影像資訊,方能有效消除此等雜訊,而這對於使用者而言不僅成本高,複雜程度也高。 The advantage of frequency domain optical coherence tomography (Fourier Domain Optical Coherence Tomography, FDOCT) in optical coherence tomography is fast imaging speed. However, when the interference signal in the frequency domain measured by the spectrometer has a cosine function in the conventional frequency domain optical coherence tomography, the interference signal in the time domain obtained by inverse Fourier transform will cause the signal to produce autocorrelation noise. (Autocorrelation Noise) and mirror noise (Mirror Noise or Conjugate Artifacts), which makes the measured sample signal ambiguous, which has a significant impact on the image quality and makes it difficult for users to interpret the real structure of the sample, or it is easy to misjudgment occurs. in conventional technology In order to solve the aforementioned problems, it is necessary to use complex optical systems, difficult algorithms, and even multiple measurements to accumulate image information of the sample, so as to effectively eliminate such noise, which is very important for users. Not only is the cost high, but the complexity is also high.
因此,習知技術的頻域光學同調斷層掃描仍有其改良之必要。 Therefore, the conventional frequency domain optical coherence tomography still needs to be improved.
因此,本發明的目的即在提供一種全域式頻域光學同調斷層掃描系統,能夠以簡單、省時、成本相對低廉的方式消除傳統頻域光學同調斷層掃描系統所產生的雜訊。 Therefore, the purpose of the present invention is to provide a global frequency domain optical coherence tomography scanning system, which can eliminate the noise generated by the traditional frequency domain optical coherence tomography scanning system in a simple, time-saving and relatively low cost manner.
