Fig. 6From: Feasibility of 177Lu activity quantification using a small portable CZT-based gamma-cameraDeviation of the estimated depth (left panels) and relative deviation in the estimated activity (right panels) for the cylindrical source in PMMA. The deviations are shown as functions of the thickness of the PMMA between the source and collimator. Top panels are results based on gross-peak count rates, and bottom panels are results when TEW scatter correction is appliedBack to article page
