Based on the linear relationship of channel data between synthetic transmit aperture (STA) and apodized plane wave (PW) firings, we previously proposed compressed sensing (CS) based STA (CS-STA) for linear array, 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 PW is usually adopted in phased...
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...
In this paper, the previously proposed compressed sensing based synthetic transmit aperture (CS-STA) was compared with synthetic transmit aperture (STA), multi-element synthetic transmit aperture (ME-STA) and the conventional focused mode in two different phantoms. The quantitative results of full width at half-maximum (FWHM) and contrast-to-noise ratio (CNR) demonstrated the merits of CS-STA. Besides,...
