Non-invasive Observation of Human Tissue Samples with Full Field Optical Coherence Tomography

摘要

In this work, we report on non-invasive observation of human esophagus, liver, and uterus samples with Full field optical coherence tomography（FFOCT）.ln imaging process, fresh human samples were fixed in formalin immediately after excision and then imaged directly without staining and cutting the samples into a serial of thin slices. Tissue microstructures of each type of normal or cancerous tissue as well as their changes with the increase of the depth beneath tissue surface can be identified in the depth-resolved images. The results demonstrate the potential of applications of the en face images in clinic practice.
