Abstract
A method for the dynamic reconstruction of time-varying activity distribution in single photon emission tomography is proposed. The method is based on the formulation of dynamical changes in the activity distribution of the object as state evolution. The reconstruction problem is then solved using a Kalman filter. The proposed method is evaluated using simulations
