Abstract
Systems and methods for implementing operation-specific impedance matching for enhancing sensitivity of an ultrasound system are described. To enhance sensitivity while using a transducer element for transmission and reception, a transducer module's architecture provides operation-specific impedance matching. Operation-specific impedance matching means that different impedances are provided for mitigating mismatch loss during transmission and reception. The impedance provided for reception can be associated with separate signal path with a smaller amount of attenuation compared to the impedance provided for transmission. In this way, the architecture enhances sensitivity of the ultrasound system by reducing an amount of attenuation experienced during reception compared to other ultrasound systems that utilize a same impedance for impedance matching during transmission and reception. With enhanced sensitivity, the ultrasound system can utilize higher frequencies and/or broader bandwidths to provide high-resolution images at farther imaging depths while meeting power-intensity guidelines.
