Frequency Domain Compressive Sampling for Ultrasound Imaging

Table 4

NRMSE between the reconstructed RF US volume and the original volume for different sampling ratios and patterns.

	Sampling	25%	33%	50%
	Θ1	0.61	0.49	0.27
	Θ2	0.69	0.57	0.40
Cubic spline interpolation	Lateral regular	1.09	1.02	0.83
