"Non-linear effects on coded excitation for microultrasound"

Lemke, Christina

Coded excitation is a well-established technique in ultrasound to construct transmission pulses with a time-bandwidth product larger than one, allowing both high signal-to-noise ratio (SNR) and better temporal resolution compared to unmodulated pulses. In our poster, we explore issues relating to coded excitation in high-frequency medical ultrasound, where the non-linear acoustic propagation in soft tissue and non-linear transducer characteristics reduce the SNR improvement and resolution achievable.
