Abstract
Many scintigraphic studies are based on the comparison of two images recorded using different traces. The processing of these Double Tracer Studies (DTS) combines the difficulties of any image comparison and those arising from the fact that the images are obtained with different tracers. This is the reason why DTS are usually analysed visually. In this case, any number of views can be used and the acquisitions can take place at different times. However, when the construction of a parametric image, such as the difference or the ratio image is planned, contraints is the imposes, in most cases, the use of radionuclides with different energies. Even if these constraits are fulfilled, difficulties still remain, such as the differences in crosstalk (or background), in absorption and in the Point Source Responces of the detector (1). In this text we present a new method of DTS processing which is based on an original and rigorous approach to the problem.
