Method and system for suppressing grating lobes using variable frequency as a function of beam steering

Abstract

Systems and methods for suppressing grating lobes using variable frequency as a function of beam steering are provided. The method includes transmitting one or more beams each at a beam steering angle. The method includes converting received echoes to generate ultrasound signals corresponding to the one or more beams. The method includes processing the ultrasound signals to generate an ultrasound image. The method includes causing a display system to present the ultrasound image. A transmit frequency and/or a receive frequency is selected based on the beam steering angle of each of the one or more beams. A larger beam steering angle corresponds with a lower transmit frequency and/or a lower receive frequency. A smaller beam steering angle corresponds with a higher transmit frequency and/or a higher receive frequency.
