From: Analysis of a deep learning-based method for generation of SPECT projections based on a large Monte Carlo simulated dataset

	Original orbit	Orbit + 2 cm	Orbit + 4 cm	Orbit + 8 cm	Orbit + 16 cm
SSIM	0.979 (0.025)	0.980 (0.024)	0.979 (0.026)	0.978 (0.026)	0.976 (0.030)
NRMSE	2.45% (1.18%)	2.43% (1.21%)	2.46% (1.23%)	2.50% (1.22%)	2.63% (1.26%)

Mean SSIM and NRMSE values between synthetic projections and noisy projections for trajectories of increasing deviations. Data in parentheses are standard deviations
