Abstract
The invention discloses a split row-column addressing method for three-dimensional ultrasound imaging, and the method comprises: for an N×N planar array, obtain the pulse-echo response distribution from fully connected two-dimensional planar array, parameters thereof comprising beam widths A' and B′ at −6 dB and −20 dB respectively, average side lobe C′, highest side lobe D′ and main side-lobe energy ratio E′; set counter K=2, split two-dimensional planar array into K regions in channel direction, determine array elements amount and connect array elements in each region; calculate the time delay according to distance between the coordinates of each region and the focus point within a scanning range of the two-dimensional planar array, and analyze the two-dimensional planar array by ultrasonic sound field simulation algorithm according to the time delay of each region. The invention can solve the prior art of low resolution, and the problem that transmitted and received beam cannot be deflected.
