Correction of circumferential and longitudinal motion distortion in high-speed catheter/endoscope ...

Osman O. Ahsen has done his Master’s and Doctoral thesis research in the Biomedical Optical Imaging and Biophotonics Group at the Massachusetts Institute of Technology with supervision from Dr. James G. Fujimoto. He has worked on development of a prototype ultrahigh speed endoscopic swept-source OCT system with micromotor-based catheters and its clinical translation to the VA Boston Healthcare System (VABHS). The combination of high speed imaging and precise distal beam scanning allowed visualization of depth-resolved en face mucosal and microvascular patterns (OCT angiography), in addition to standard cross-sectional imaging, enabling new clinical applications of endoscopic OCT. Osman is currently working as a postdoctoral research fellow at the Wellman Center for Photomedicine with supervision from Dr. Guillermo J. Tearney. His current research interest is on developing novel imaging techniques for coronary artery disease.
