In addition to changes in the tissue architectures, angiogenesis has been demonstrated to play an important role in the progression of oral neoplasm. In this study, we have developed a micromotor imaging catheter allowing high-speed and wide-field OCT and OCT angiography imaging of the oral mucosa. Leveraging polarization diversity detection, it ensures an optimal detection of the OCT signal for the entire circumference. ? COPYRIGHT SPIE.
