Abstract

Process of representation in plan of the distribution of a radioactive tracer that emits energy radiation a in the presence of at least another tracer that emits energy radiation b, a procedure of the type that includes the detection of the radiations of energies a and b in determined points distributed in the same plane of observation, and the determination of the difference of the intensities of the radiations a and b at each point, characterized in that it includes: a) in a first stage, the scanning of said observation plane by a radiation detection probe of energies a and b, providing impulses whose amplitude as a function of the energy of the radiation, and whose counting index is proportional to the intensity of this radiation, the impulses being directed to a spectrometer with two channels that effect the separation between the corresponding impulses to the energy and the impulses that correspond to the energy b, which pass, respectively nte, to one, a, or the other, b, of said channels, and the simultaneous recording of coded signals that translate two coordinates that define the position of the probe and of said pulses passing to each of said channels, to the output of the spectrometer; b) in a second step, the determination of the difference of the counting indices of the pulses recorded, respectively, at the output of the two channels a and b of the spectrometer and the location, based on said coded signals, of an organ of transcription that provides an information, function of said difference, in order to make this organ perform a sweep in analogous plant that of the detection probe in the first stage.
