题目：Mathematical Problems in Spatiotemporal Dynamic Medical Imaging    

摘要：Spatiotemporal dynamic medical imaging is critical in clinical applications, such as tomographic imaging of the heart or lung. As an example, in PET/CT cardiac imaging, when data is acquired over a relatively long period of time (often in the range of minutes), the unknown motion of the organs leads to severe degradation in image quality. Furthermore, to reduce the radiation or conduct fast scanning, the low-dose or sparse sampling is often required. Hence, the image reconstruction with high spatial and temporal resolutions becomes particularly important and very challenging, which can be actually formulated as a time-dependent dynamic inverse problem. We will talk about the recent advances on mathematical modeling and computation for image reconstruction in spatiotemporal imaging, and the existing mathematical problems.
