The effect of attenuation map, scatter energy window width, and volume of interest on the calibration factor calculation in quantitative 177Lu SPECT imaging: Simulation and phantom study

•Dependency of 177Lu SPECT calibration factors on phantom size.•Influence of volume of interests on 177Lu SPECT calibration factors.•Effect of attenuation maps on 177Lu SPECT calibration factor.•ESSE performed better than TEW in simulations.•Scatter energy windows are suggested for improved TEW scat...
