My research interests are mathematical innovations in biomedical imaging and image processing, with x-ray computed tomography, optical tomography and multi-modality biomedical imaging as the major applications. I am honored to work with colleagues from mathematics, statistics, physics, computing technology, biology and clinics to develop theories, methods and software and hardware implementations for biomedical applications. I have been the PI/MPI/Co-PI of large-scale projects funded by the National Science Foundation of China, Ministry of Science and Technology of China, Ministry of Education of China, and Sino-German Center.

Selected Contributions

[Iterative Image Reconstruction Algorithms] With the increasing complexity of imaging modalities, iterative reconstruction methods become more and more useful because a closed form solution is hardly available. With collaborators, we proved the convergence of SART (simultaneous algebraic reconstructive technique), which is one of the most popular iterative image reconstruction algorithms, and established its convergence dependence on initial value. This work was extended to a unified framework for block-iterative Landweber algorithms. Representative publications in this work are

[Bioluminescence Tomography] Bioluminescence tomography (BLT) is an optical tomography technique developed since 2004 to image in vivo 3D distributions of bioluminescent probes for preclinical molecular imaging of small animals. With collaborators, we published the first journal paper on the theoretical aspects of BLT. There are ~20 groups in this area, and many bioluminescence imagers for studies on animal models of almost all human diseases. The representative publication in this work is

[Regularization Techniques] Imaging and image processing problems are typical ill-posed inverse problems, for which the regularization technique with priors or other regularization approaches within the general Bayesian inference are necessary. With collaborators, we developed the theory and algorithms of higher order total variations, which is a non-trivial extension of the widely used total variations regularization, and has been applied successfully to interior tomography of x-ray CT and SPECT.   Our recent work is the regularization properties of the Mumford-Shah functional, which can used to simultaneously reconstruct image and its segmentation.  The edge prior can help improve the reconstructed image quality, which is missed in other conventional priors. The representative publication in this work is

[Hardware Implementation] We have established an energy-efficient and memory-optimized implementation with FPGA for our asynchronous parallel iterative reconstruction algorithm for the regularization of Mumford-Shah functional. We have evaluated the performance in terms speed and image quality for low dose spiral x-ray CT in clinics and electron transmission tomography. For low dose spiral x-ray CT, our implementation can reach the same image quality under the same low dose and with a reconstruction speed for clinical applications.
