Fig. 3From: Evaluation of reconstruction methods and image noise levels concerning visual assessment of simulated liver lesions in 111In-octreotide SPECT imagingVisual demonstration of the disappearance of simulated lesions when placed in a region of low activity concentration. The upper and lower rows show reconstructions without and with the simulated lesion, position denoted by the red circle, respectively. K denotes the right kidney.
