Method and apparatus for reducing noise in a sequence of fluoroscopic images

A radiological apparatus comprising:

• means for radiographic exposure to provide a sequence of images;
• means for emission of radiation;
• and
• means for reduction of noise in the images of an object in motion comprising:
• differentiation of the pixels of the image between pixels in motion and fixed pixels;
• and
• processing by an operation of time filtering of the fixed pixels, for each pixel of the image;
• the differentiation between pixel in motion and fixed pixel is performed as a function of the result of a detection of the movement during the course of which, in a zone of the image covering a set of pixels in the vicinity of the pixel, the existence or respectively the absence of motion of the object relative to a preceding image is detected.
