We propose a multimodal endoscopic system based on white light (WL), multispectral (MS), and photometric stereo (PS) imaging for the examination of colorectal cancer (CRC). Recently, the enhancement of the diagnostic accuracy of CRC colonoscopy has been reported; however, tumor diagnosis for a variety of lesion types remains challenging using current endoscopy. In this study, we demonstrate that our developed system can simultaneously discriminate tumor distributions and provide three-dimensional (3D) morphological information about the colon surface using the WL, MS, and PS imaging modalities. The results demonstrate that the proposed system has considerable potential for CRC diagnosis.
我们提出了一种基于白光（WL）、多光谱（MS）和光度立体（PS）成像的多模态内镜系统，用于结直肠癌（CRC）检查。最近，已有报道称结肠镜检查对CRC的诊断准确性有所提高；然而，使用当前的内窥镜检查对各种病变类型进行肿瘤诊断仍然具有挑战性。在本研究中，我们证明了我们开发的系统可以同时区分肿瘤分布，并使用WL、MS和PS成像模式提供有关结肠表面的三维（3D）形态信息。结果表明，所提出的系统在CRC诊断方面具有相当大的潜力。
