Abstract
In this work we present a method to estimate and compensate the local motion of a hot region in a PET list-mode acquisition directly on the measured LORs. The method is applicable for arbitrary motion patterns. Different shapes of the hot regions, different contrast ratios and different count statistics are examined. In a simulated anatomical data set the algorithm has recovered 98% of the true activity in a lung lesion with respiratory motion.
