Fig. 3From: Quantitative 177Lu SPECT/CT imaging for personalized dosimetry using a ring-shaped CZT-based cameraRecovery coefficients for the spherical inserts of the NEMA phantom with cold background as a function of the number of iterations (1 subset) for GE-OSEM, Q.Clear and Q.ClearRDP. For the factory protocol, RCs with cold background were found equal to 26%, 37%, 49%, 54%, 58% and 66% for the 10 mm, 13 mm, 17 mm, 22 mm, 28 mm and 37 mm sphere, respectivelyBack to article page
