Abstract
A process and system for improving a digital image of an object defined by pixels, acquired at the instant t and generated from an X-ray detector receiving X-rays emitted by a source. The process includes: determining a predicted image of the object at the instant t as a function of the images of the object acquired at the instants t−i, i being a positive whole number greater than or equal to 1, and moving of each of the layers constituting the image acquired at the instant t, the number of layers being previously fixed and the moving of each of the layers being previously determined; and generating a visualized image corresponding to a weighted sum of the predicted image and the image of the object acquired at the instant t, so as to attenuate the noise of the image of the object acquired at the instant t.
