I am a Ph.D student in Graduate School of Global Information and Telecommunication Studies Waseda University, Japan, from 2009 until now. My research is focused on medical image processing, and current topic is the image-guidance system for fetal CDH surgery, where we will use real-time 3D ultrasound images and 3D magnetic reasonance images, as well as simulate the movement of a surgical manipulator. My former research topic is about the segmentation of human brain MR images by fuzzy clustering methods and Markov random field, when I was a master in Southeast University, China, from 2006 to 2009.
