Optimization of Contrast-to-Tissue Ratio by Adaptation of Transmitted Ternary Signal in Ultrasound Pulse Inversion Imaging

Table 1

CTR measured if the signal transmitted is (i) a ternary signal at two-thirds of the central frequency 𝑓_𝑐 of the transducer, (ii) a ternary signal at the optimal frequency 𝑓_opt, or (iii) the optimal ternary command.
