A multi-isotope study is carried out using a plurality of imaging agents which are imaged simultaneously. The information obtained is weighted using as many energy weighting functions as there are isotopes. The weighting reduces "crosstalk" between each of the single-isotope images which are produced as a result of the study. This produces improved results in, for example, dual-isotope (Tc-99m and Tl-201) myocardial perfusion studies. |
