Abstract
A method and device for sampling a fragment of tissue in which a contrast medium is injected into an organ to be examined and highlights parts containing that contrast medium in an image obtained by emitting a beam of X-rays. At least one pair of radiographic images is captured from a first position and a second position of an X-ray emitter during a phase of increasing attenuation due to the contrast medium. A specific area is identified from the pair of images in which a tissue fragment is to be sampled. The images of the pair of images are combined to determine the three-dimensional coordinates of the specific area.
