Comparison between the relative activity of 68Ga obtained with the detector using the gamma spectroscopy analysis of a mixture of 68Ga and 18F (aGa,D) and the theoretical relative activity (aGa,A). The data collected from the 1-min acquisitions were analyzed entirely (gray squares) and partially (following scheme given in Eq. (3), black dots). Pearson’s r correlation of the datasets with the true values (aGa,A) are r = 0.97 and r = 0.91 respectively. Dashed blue line represents the identity line
