Bio

I earned an M.S.in Mathematic and Applied Mathematic in Chongqing University and entered the Institute of Image Processing and Pattern Recognition in Xi’an Jiaotong University in the fall of that year. My main research interest is few-view CT reconstruction algorithm based on compressed sensing. I am currently involved in project that low-dose CT reconstruction with learned Dictionary. My major work in this project is developing a convergent algorithm for few-view CT reconstruction with learned Dictionary and developing an approach to find the optimal regularization parameter in the proposed algorithm.
