B-mode images of an RMI phantom including cysts and point targets using 192-element LCA probes operating at 3.6 MHz: (a) control 1-layer PZT5-H (contrast: hyperechoic = −0.28, hypoechoic = 0.42) and (b) 3-layer low-loss PZT4 composite (contrast: hyperechoic = −0.25, hypoechoic = 0.41). Note the similar image quality.
