More Information
Summary:Methods for suppressing grating lobes using variable frequencies according to beam steering are provided. The method comprises the following steps: transmitting one or more beams, wherein each beam is transmitted at a beam steering angle; converting the received echoes to generate ultrasonic signals corresponding to one or more beams; processing the ultrasound signal to generate an ultrasound image; causing a display system to present the ultrasound image; a transmit frequency and/or a receive frequency is selected based on a beam steering angle of each of the one or more beams, a larger beam steering angle corresponding to a lower transmit frequency and/or a lower receive frequency, and a smaller beam steering angle corresponding to a higher transmit frequency and/or a higher receive frequency. The invention also provides a system for suppressing grating lobes by using variable frequencies according to beam steering. 本发明提供了根据波束转向使用可变频率来抑制光栅波瓣的方法。该方法包括：发射一个或多个波束，每个波束以波束转向角度发射；转换所接收的回波以生成对应于一个或多个波束的超声信号；处理超声信号
