Abstract: A method for representing the spatial distribution of radioactive elements of radioactively labeled samples, by means of a screen of the erasable phosphor type, in which the labeled samples are placed near this screen in order to generate thereon a latent electronic image formed by the .beta. radiation or primary electrons generated by the radioactive elements. The primary electrons emitted by the radioelements are accelerated to an energy level lying between 20 keV and 1 MeV by means of an electric field E applied between the space separating the sample and the screen. The primary electrons subjected to acceleration in the space are confined, so as to limit the lateral excursion of these primary electrons. The latent image is formed, on this screen, from the confined and accelerated primary electrons. The primary electrons can generate low energy secondary electrons in CSI screens which are thus accelerated and focussed to give enlarged images onto a screen.

Each of at least two kinds of the radiation, each of which has been produced at the thus adjusted tube voltage, is irradiated to one of at least two stimulable phosphor sheets, and radiation images of the object are thereby stored on the stimulable phosphor sheets.

Abstract: Using storage phosphor recording media, two exposures are made of a sample containing two target substances tagged with different radiative emitters, for example 32-P and 35-S. The first exposure, image 1, is of the sample directly on the phosphor screen. The second exposure, image 2, is made with the appropriate absorption material between the sample and screen. Both images are captured. By using simultaneous equations isotope contributions of each label can be determined. Quantitative assessment of the contributions of the isotopes, and hence the target substances, are made by calculating isotope efficiencies both with and without the absorption filter.
