Chiba University, Japan

Hideaki Haneishi received his BS degree from the University of Electro-Communications in 1985 and received his M.S. and Ph.D. degrees from the Tokyo Institute of Technology, in 1987 and 1990, respectively. He joined Chiba University as a Research Associate in 1990. While continuing his career in Chiba University, he was invited as a Visiting Research Scientist at the Department of Radiology, University of Arizona, from October 1995 to July 1996. He is currently a Full Professor and the Director at the Center for Frontier Medical Engineering (CFME), Chiba University. He has published more than 150 papers in refereed journals with more than 3900 citations (Google Scholar). His research interests include spectral imaging, biomedical optics, image reconstruction and motion picture analysis in medical field. Prof Haneishi has been expanding and strengthening his international research network while serving as PI of the Core-to-Core Program named ^International Network of Multi-modal Medical Engineering for Precision Medicine ̄ (2017-2022) adopted by the Japan Society for the Promotion of Science (JSPS). In this program, researchers from Finland, China, Canada, Thailand, USA, France and New Zealand study together for collaboration. He is also an active member of Chiba Central Toastmasters Club, a branch of Toastmasters International, a nonprofit educational organization aimed at public speaking and leadership skills through a worldwide network of clubs.


Speech Title: "Visualization of 3D Vascular Structure from OCT Images"


Abstract: Problem: Optical coherence tomography angiography (OCTA) is a three-dimensional (3D) imaging technology used to emphasize the contrast of vascular structures in OCT images. In fact, however, the vascular pattern in the obtained 3D OCTA image has serious tailing artifacts in the depth direction, which makes the visualization of real 3D vascular structure difficult. Method: We developed a method for extracting vascular structure accurately. It consists of extraction of the centerlines of the vascular structure in en face images, template matching to 3D OCTA images to acquire the image that emphasizes the vascular center, and depth estimation along the centerline. Experiment and Result: Using an OCT system (WP-OCT 800nm, Wasatch Photonics), we obtained OCTA images of the dorsal dermis of mice. The proposed method was applied to the OCTA images. The results demonstrated that the proposed method well achieved the visualization of 3D vascular structure.
