Quantitative Accuracy of Low-Count SPECT Imaging in Phantom and In Vivo Mouse Studies
Figure 1
(a) Phantom used in imaging studies. The 3 microcentrifuge tubes were mounted in the centre of a polystyrene holder. The three activity concentrations were approximately 20, 10 (In111)/5 (Tc99m), and 1 MBq/250 μL. (b) Reconstructed image slices with volume-of-interest drawn in the transaxial plane highlighted in green.
