In clinical applications using large apertures, a significant number of phased array elements may be blocked due to discontinuous acoustic windows into the body. These produce undesired beamforming artifacts, degrading spatial and contrast resolution. To minimize these an algorithm multiple receive beams total-least-squares method is proposed. Simulations experimental results show that this can effectively reduce imperfections in point spread function imager. Combined with first-and...
Aberration correction methods for 1-D arrays have been extended 2-D arrays. Particular emphasis has placed on aberration anisotropic arrays, where local phase errors are estimated using correlation processing of signals from unequally sized elements. Unwrapping these estimates over the array also investigated. A very practical method appropriate pipelined beam forming developed. Simulation results demonstrate that yields accurate corrections an array. Moreover, show accuracy is relatively...
Due to the discontinuous nature of acoustic windows into body, a set phased array elements may be inactive in clinical applications. They produce undesired beamforming artifacts and degrade spatial contrast resolution. To minimize artifacts, an algorithm using multiple receive beams total-least-squares method is proposed. Results show that this can effectively reduce imperfections point spread function imager. Combined with local scatterer statistics, modified for compensation on distributed...
