Fig. 3From: Accuracy of 177Lu activity quantification in SPECT imaging: a phantom studyQuantification errors for phantom inserts with different shapes and volumes scanned in cold water and error distribution (b) for both scatter correction methods, TEW and APDI (b). The horizontal dashed lines in (a) mark the maximum and minimum deviations from the truth. The boxes in (b) represent the range of variation (interquartile range-IQR) of the distributionsBack to article page
