Abstract
An image reconstructing apparatus wherein the object under examination is irradiated in at least one direction to provide projection data, and the provided projection data is optically processed to form a reconstructed image representing the internal information of the object. An image associated with the projection data is formed and stored in the storage medium. The stored image is optically read out of the storage medium. The read out stored image which corresponds to one direction of irradiation is integrated at a time to produce sum data. The sum data and projection data corresponding to the same direction of irradiation are compared to form correction data. An image associated with the correction data is formed and optically superposed on the stored image in the storage medium corresponding to the same direction of irradiation, to produce the reconstructed image.
