    摘要: 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.

    摘要: A spatial light modulation device includes a spatial light modulation tube and converts a one-dimensional photoelectron image into a two-dimensional electron image, rotating the two-dimensional electron image, subjecting the rotated two-dimensional electron image and a previously stored electron image to addition or subtraction, and stores the electron image thus processed. An image reconstructing apparatus includes: projection means for detecting as projection data a projection of internal information of an object; the spatial light modulation device which produces and stores a corrected reconstructed image on the basis of a one-dimensional correction data image and a previously stored reconstructed image; optical reading means for reading out the reconstructed image form the spatial light modulation device; summing means for integrating parts of the readout reconstructed image to produce sum data; and comparison and correction means for subjecting the projection data and the sum data to comparison to form the one-dimensional correction data image.
