Tissue harmonic imaging requires transducers with which bandwidth characteristic?

Explanation:
Tissue harmonic imaging depends on the higher-frequency components generated by the nonlinear propagation of ultrasound in tissue. To detect and use those harmonics effectively, the transducer must respond over a wide range of frequencies. A broad bandwidth allows the transducer to transmit at the fundamental frequency and receive the higher harmonics with good sensitivity, while a narrow bandwidth would miss much of the harmonic content and degrade the image. Impedance or a very low Q aren’t the defining factors here, and while a low Q can contribute to broader bandwidth, the key requirement is broad bandwidth.
