The stretched-pulse mode-locked laser technology for Optical Coherence Tomography
About the Seminar:
One of the new imaging approaches introduced by a group of scientists under the leadership of James G. Fujimoto in 1991 is the Optical Coherence Tomography (OCT) technique. With the new noninvasive imaging model, high-resolution (1-15 μm) 3-dimensional (3D) images can be obtained from biological tissues up to a depth of approximately 3-mm without the need for bio-imaging dyes. Because of these properties, OCT is becoming an attraction point that can be a diagnostic tool in the field of medical imaging. Wavelength-swept OCT (SS-OCT) demonstrates that this new technique can provide higher sensitivity and faster (MHz) imaging. Moreover, the laser source characterizes critical parameters such as axis resolution, A-line rate, coherence length, and sensitivity level. Therefore, with the development of laser sources, it is thought that this imaging model will lead to radical changes in medical applications such as cardiology, flow and perfusion, ophthalmology, elastography and especially endoscopy. At this point, we present the stretched-pulse mode-locked laser technology, which we contribute to the development of internationally with the projects we carry out in our research laboratory.
About the Speaker:
Serhat Tozburun received his B.S. degree in Physics from Middle East Technical University in 2005, an M.S. degree in Physics from Koç University in 2007, and a Ph.D. degree in the Optical Science and Engineering from the University of North Carolina, Charlotte in 2012, respectively. In his Ph.D. dissertation research, he worked on optical stimulation of cavernous nerves lying on the prostate surface, using infrared laser radiation as a potential alternative for intraoperative identification and preservation of the Cavernous nerves to conventional nerve mapping devices.
After graduation, he joined the Wellman Center for Photomedicine at Massachusetts General Hospital and Harvard Medical School to participate in innovative research studies of the development of optically subsampled optical coherence tomography and a rapid, phase-stable optical coherence tomography system. At Wellman Center, he also focused on developing a method using novel apparatus for the treatment of Barrett’s esophagus, which is a precancerous condition of the esophagus and associated with esophageal cancer.
Currently, he is a faculty member at Dokuz Eylul University and is appointed as the principal investigator at İzmir Biomedicine and Genome Center (IBG). At IBG, He established the Biophotonics and Optical Imaging Research Group in 2016. The broad goal of the research group is to develop and implement optical techniques and non-invasive optical coherence imaging modalities to address biomedical challenges.
Dr. Tozburun serves as a reviewer of the Journal of Biomedical Optics, Optics Express, Biomedical Optics Express, Optics Letter, Applied Optics and Current Molecular Imaging. He is a Marie Skłodowska-Curie Actions (MSCA) fellow. He is also a member of the Institute of Electrical and Electronics Engineers – IEEE, the Optical Society of America – OSA, and the International Society for Optics and Photonics – SPIE. He has been awarded a 2012 Optics and Photonics Scholarship by SPIE for his potential contributions to the fields of optics, photonics, or related field, a 2016 Eser Tumen Outstanding Achievement Award by Fevzi Akkaya scientific activities support fund (FABED), a 2018 Young Scientist Award Program (GEBIP) Grantee by Turkish Academy of Science (TUBA), and a 2020 Young Scientist Awards Program (BAGEP) Grantee by Science Academy.
