Quantitative validation of Monte Carlo SPECT simulation: application to a Mediso AnyScan GATE simulation

EJNMMI Physics

Table 6 The sensitivity for the emission window (EM) and scatter window (SC) images of the \(^{99\text {m}}\)Tc phantoms with standard uncertainties

Isotope	Phantom	Window	Sensitivity (counts/(s\(\times\)MBq))		Sensitivity ratio
			Simulation	Experiment	(Sim/Exp)
\(^{99\text {m}}\)Tc	Cylinder	EM	36.33 ± 0.73	37.39 ± 0.33	0.972 ± 0.021
		SC	8.74 ± 0.19	7.865 ± 0.071	1.111 ± 0.026
\(^{99\text {m}}\)Tc	NEMA	EM	24.77 ± 0.50	27.06 ± 0.24	0.915 ± 0.020
		SC	4.464 ± 0.095	4.376 ± 0.039	1.020 ± 0.023

The last column gives the sensitivity ratio (simulation/experiment) which was used to normalise the simulation to validate projection and profile data
