In photoacoustic imaging, as in many high resolution modalities, the major bottle neck is the acquisition time of finely spatially sampled data. In particular for imaging of dynamical processes, this results in incomplete data. In this talk we are going to discuss different aspects of variational methods for photoacoustic imaging using spatio-temporal regularization via optical flow constraint which allow us maintaining good quality of the reconstruction from severely subsampled/compressed dynamic data.
