Micro-optical coherence tomography (μOCT) in vivo

We have developed a Micro- optical coherence tomography (μOCT) for in vivo use. We extended line width of the light source and have achieved a longitudinal resolution of 1.9μm in free space and 1.38μm in tissue. In vivo imaging was conducted using zebra fish larvae and cellular structures such as red blood cells in tail artery can be observed.
