Patent ID: 7106894

Claim:
A method of treatment of a sequence of x-ray images of a body, comprising: acquiring an image sequence including a current image and a preceding image, filtering the preceding image, and applying a displacement vector to the preceding filtered image, thereby defining a displaced preceding filtered image; elaborating for each acquired current image of a current filtered image from the acquired current image and from the preceding filtered image; and visualizing the elaborated and filtered image sequence; wherein for each acquired current image, a displacement of the current image is determined relative to the acquired preceding image in an image acquisition plane, the displaced preceding filtered image is elaborated by spatially displacing the preceding filtered image, taking the displacement of the current image into account, and the current filtered image is elaborated by a weighted average by applying a first weighting coefficient to the displaced preceding filtered image and a second weighting coefficient to the acquired current image, so as to improve the quality of the images visualized.
