From: Phantom and clinical evaluation of bone SPECT/CT image reconstruction with xSPECT algorithm
Reconstruction plots showing quantitative distribution in TBR1 (a), 2 (b), 4 (c), and 10 (d). The filled and unfilled symbols indicate maximum and mean activity concentrations, respectively. The dotted line is the actual activity concentration of phantom. Filled and unfilled triangles indicate Flash 3D (F3D). Filled and unfilled circles indicate xSPECT Quant (xQ). Filled and unfilled squares indicate xSPECT Bone (xB)
