X-ray Tomographic Imaging and Applications Enabled by Advanced Algorithms

The presentation will first highlight some of the recent advances in optimization-based algorithms for image reconstruction in tomographic imaging, especially in X-ray tomographic imaging, and will then focus on discussing the challenges in adequately applying the algorithmic advances to possibly benefiting real applications of clinical or practical significance. A series of real-data examples in X-ray tomography relevant to imaging tasks in radiation therapy will be used for illustrating how optimization-based algorithms may be exploited for enabling the development of imaging systems and workflows tailored to specific applications of practical merit in medicine and other areas. The presentation will also clarify some seemingly confusing issues concerning, e.g., compressive sensing (CS) in image reconstruction and image/signal processing. If time allows, the presentation may touch upon implications of optimization-based reconstruction for PET and MRI imaging.
