The distribution of normalized error in the estimated uptake as a function of SBR values for the circular-region radius of a 14 mm, b 12 mm, c 10 mm and d 7 mm. The normalized error for the kth circular region, nth noise realization and sth object realization was computed by: \(\dfrac{{\hat{y}}_{sk}^{n}-y_{sk}}{y_{sk}}\). The distributions were generated by kernel estimator
