aQuantification of molecularly targeted radiotracer uptake in the myocardium from SPECT remains challenging in part due to potentially low levels of focal tracer uptake of presently available molecularly targeted agents and further degradation of cardiac SPECT by extracardiac radioactivity and partial-volume...
Radioactivity measurement for input support device, input support method and input support programPROBLEM TO BE SOLVED: To provide an input support device capable of improving operability by an operator when performing radiation measurement, preventing wrong input, and improving efficiency of an input ...
The Geosphere computer model described is used to compute the amount of radioactivity released per year (the release rate) to a receiver from a repository in a geologic formation through which ground water is flowing. The release rate is computed as a function of time, so that a ...

Run-off is thus a secondary transfer of atmospheric radioactivity to the sea. About 9% to the 90Sr inventory on land will be removed by run-off. For 137Cs the figure is about 2% (Yamagata et al., 1963). As the total deposits of global fallout 90Sr and 137Cs are 622 and 948 PBq...
Poor estimation of spill-in effects can lead to an overestimation of the vessel radioactivity concentration and bias IDIFs, particularly at the tail-end of the curve. For IDIFs which are best suited for graphical-based kinetic analysis, overestimating the tail-end of the curve further minimizes ...
Positron emission tomography (PET) with O-labeled water (H O) facilitates the visualization and quantification of blood flow in clinical investigations and also in small animals. The quantification of blood flow requires an input function, which is generally obtained by measuring radioactivity in arter...
