Fig. 3

Illustration of the activity mask dataset. For each activity mask, the transversal (top) and sagittal sections (bottom) are shown. First row from left to right: hot Jaszczak with cold random shapes, chessboard pattern, rod pattern, cross pattern, stripe pattern, NEMA phantom spheres. Second row from left to right: example random shape, example Fourier series F(x, y, z), random shape with non-uniform activity distribution. The plot shows the distribution of the maximum activity concentration (orange, bottom and left axes) and volumes (blue, top and left axes) of the activity distributions contained in the dataset. The dashed green curve represents the distribution of the maximum activity concentration of 104 peritherapeutic 177Lu SPECT/CT examinations (bottom and right axes)
