Gastric and colon cancer imaging with swept source optical coherence tomography

Swept source Optical coherence tomography (SS-OCT) is used to image the cancer samples of 12 gastric and colon cancer patients, including 5 gastric cancer and 7 colon cancer patients. The OCT images and histopathology sections show obvious difference between the normal tissue and cancer tissue. The regular layered structure can be seen at OCT images of normal tissue, while the disordered textures and destroyed layers' architectures preserve as the common features of cancer tissues' images. The variation of texture matched between the OCT images and ordinal pathological sections.
