Relative SNR of tailored VFA scheduling compared with MAPSS. A, The VFA trains for tailored VFA scheduling (solid lines) and MAPSS (dashed line) at VPS = 64 for the imaging parameters listed in Table 1. The value of α1 is greater for tailored VFA scheduling than MAPSS, which results in relatively greater signal. B, The difference in α1 between the two methods becomes greater as VPS increases. C, Relative SNR of tailored VFA scheduling versus MAPSS, assuming that SNR is proportional to sin(α1). At VPS = 32, 64, 128, and 256, tailored VFA scheduling has, respectively, 1.2×, 1.4×, 2.0×, and 4.5× greater SNR than MAPSS
