Reconstruction Sharpness and, Noise Level Measurements for the Physical Phantom Study

Motion Phase	Motion rate^† (bpm)	View-angle sampling (view angles)	Pseudo PSF width (mm)		Pseudo PSF shift (mm)		Noise standard deviation (10^–4mm^–1)
			Vertical	Horizontal	Vertical	Horizontal
A	75	17	0.45	1.02	0.45	0.60	2.2
B	75	17	0.40	0.36	0.49	0.50	2.0
C	75	17	0.51	1.1	0.48	0.68	2.4
D	75	16	0.50	0.95	0.42	0.53	1.9

^†

Assuming an acquisition time of 14 seconds.

The ROI used for the rRMSE measurements is shown in Fig. 9.

Both the prior image and the reference images have noise standard deviations of 4.6 × 10^–4 mm^–1.
