Abstract: Based on the high frame rate demand of ultrasound imaging, a beamforming algorithm based on multi-line acquisition delay multiply and sum(MLADMAS) was proposed. This algorithm was based on a method named multi-line acquisition; there are more than one receiving lines from a single transmission line, then the lower complexity DMAS beamforming was used in parallel to obtain several receiving lines simultaneously. The simulated results showed that the frame rate of MLADMAS was 2 times higher than that of DAS with a better image quality. The quantitative indexes FWHM, PSL and CR were improved by 28.49%, 26.29% and 26.06%, respectively. The image quality could be further improved when apodization was applied.

Key words: phased array, ultrasound imaging, multi-line acquisition, delay multiply and sum, high frame rate
