ULTRASOUND SYSTEM WITH ASYMMETRIC TRANSMIT SIGNALS |
摘要 |
An ultrasound system drives the elements of an ultrasound probe with asymmetric transmit signals which reinforce poling of the probe transducer. The use of asymmetric transmit signals enables a transducer element to withstand a significantly higher RF transmit voltage without degradation, which in turn enables higher acoustic output and improved reliability. This is particularly beneficial with single crystal transducer material when used to generate high energy pressure waves of long duration such as shear wave push pulses. |
