Abstract:
1. A method of sampling a fragment of tissue, comprising: obtaining an initial pair of radiographic images of an organ to be examined from a first position and a second position by a radiation emitter before injecting a contrast medium; injecting a contrast medium into the organ to be examined; obtaining at least one pair of radiographic images from the first position and the second position by the radiation emitter during a phase of increasing attenuation due to the contrast medium; obtaining at least one second pair of radiographic images from the first position and the second position by the radiation emitter at the end of the phase of increasing attenuation due to the contrast medium; in response to the at least one pair and the at least one second pair of radiographic images, identifying a specific area in which the fragment is to be sampled; and combining images of the initial pair of radiographic images, the at least one pair of radiographic images, the at least one second pair of radiographic images, or any combination comprising at least two of the foregoing pairs of images to determine the three-dimensional coordinates of the specific area.
