摘要
The present invention discloses an image reconstruction method, an image reconstruction device and a monitoring system for monitoring core debris state. The method comprises the steps of: establishing a system model of a monitored object, and obtaining a system matrix between the projection data and an image of cosmic ray muons that penetrate through the monitored object; initializing the image; obtaining the real projection data of the cosmic ray muons that penetrate through the monitored object; performing an algebraic iteration on the image based on the initialized image, the real projection data and the system matrix; and obtaining a final image by combining the reconstructed image of the core debris state obtained by algebraic iteration with the system model of the monitored object. According to the technical solution of the invention, the core state can be monitored rapidly and accurately, so that an emergency commander can accurately know the accident process in time according to the reconstruction result of the invention, thereby a more effective accident mitigation measures can be proposed.
