Endoscopic optical coherence tomography with a micromachined mirror

This paper presents experimental results of an endoscopic optical tomographic (EOCT) imaging system based on a micromachined mirror. Due to the use of the micromachined mirror, the endoscopic OCT system is highly suitable for non-invasive imaging diagnosis of a wide variety of inner organs. Ex-vivo imaging of rabbit bladder was performed. The microstructures of the bladder walls could be delineated with a traverse resolution of 20 /spl mu/m and an axial resolution of 10 /spl mu/m. The results have demonstrated the potential of EOCT for early diagnosis of bladder cancer and precise guiding of excisional biopsy.
