Title: Motion‐Corrected Dynamic Tomography


We will discuss the problem of reconstructing the density of a moving subject from sparse angular measurements at each time step, a problem naturally appearing in dynamic CT and in PET imaging. After a brief introduction to inverse problems in medical imaging, we present

appropriate models for the motion together with advanced variational regularization techniques for jointly reconstructing motion and images.

We discuss their mathematical properties, numerical solution, practical applications, and some

limitations (sample rate vs. motion speed, initial guesses). Finally we comment on the potential incorporation of (partial)motion information from other modalities as e.g. used in PET ‐MR image
