Based on the linear relationship of channel data between synthetic transmit aperture (STA) and apodized plane wave (PW) firing, we previously proposed compressed sensing (CS) based STA (CS-STA) for linear array (Liu et al, IEEE TMI 2017), which achieves higher frame rate and higher contrast-to-noise ratio (CNR) than STA while maintaining its high resolution. Because diverging wave (DW) instead of...
A novel beamforming technique, named compressed sensing based synthetic transmit aperture (CS-STA) is proposed to speed up the acquisition of ultrasound imaging. This technique consists of three steps. First, the ultrasound transducer transmits randomly apodized plane waves for a number of times and receives the backscattered echoes. Second, the recorded backscattered echoes are used to recover the...
