Claim One:
1. A process for restoring images of a moving object, comprising the steps of: making measurements of a property of the object by detectors at different times; obtaining a sequence of original images with a reconstruction process from the measurements for each of said different times; estimating displacements of the object with time in said original images; improving a sequence of restored images, the restored images being composed of points, a value of the property being associated to each of the points, wherein: an error function is used, which is a sum of a time regularization term, a space regularization term and a measurements adequation term; for each point of the restored images, the time regularization term expressing differences of the value of the property between this point and points of other restored images in the sequence which are associated to said point through the estimated displacements of the object with time; the space regularization term expressing differences of the values of the property between said points and neighbour points in a same restored image; and the measurements adequation term expressing differences between the measurements and projections of the restored images made in inverting the reconstruction process; the values of the property at points of each restored image being modified in an iterative manner in order to progressively diminish a value or the error function for said restored image.
