An apparatus for visualizing a body by detecting the radiation of a tracer contained in this body and consisting of positron emitters, comprising: detection cells situated on each side of the body and permitting detection of the gamma particles released by each positron emitter in two opposite directions; means for locating cells arranged in pairs opposite one another, on each side of the body, each pair of opposing cells being located on a straight line passing through a positron emitter; means for coding the location of said pairs of opposing cells; means for memorizing these coded location signals; means for processing these coded and memorized signals; visualization means, controlled by the processing means, for visualizing the image of the body from the different signals coded and memorized, further comprising: means connected to the detection cells for measuring the differences in travel time of the gamma particles emitted by each emitter, towards corresponding pairs of opposing cells; means for coding the values of these differences in travel times , these coding means being connected to the memorizing means for also memorizing coded signals representing the values of the differences in travel times, and so that the processing means receive the additional coded and memorized values representing the differences in travel times, for visualizing the image of the body.
