Abstract: Method and apparatus for the management of the dynamics of a digitized radiological image of the type comprising a radiation source and a means of detection of the radiation source after it has crossed an object of interest, the means of detection capable of converting the radiation source into a digital electronic signal, including means for defining an intensity threshold from a so-called digitized input image, means for deducing therefrom an algebraic compensation image to raise the pixels of level below the threshold, and means for adding the input image and the compensation image, in order to obtain a compensated image which preserves the differences and the real relations between internal structures of the object of interest. The method and apparatus is useful in X-ray radiological imaging of internal organs of the human body.
