More Information
Summary:The invention provides a method for rebuilding Kallman filtering image in PET imaging. The method includes steps as follows: obtaining a sinusoidal chart of an original projective line through PET positron emission faultage scanner, establishing a state space system, getting radioactivity activity distribution through the Kallman filtering method based on the state space and rebuilding image. Themethod rebuild PET image by using the Kallman filtering method based on the state space system which can increase the rebuild image quality efficiently; compared with the prior rebuild method, declination and dispersion of the rebuild result are increased greatly.
