Ultrasound Imaging Based on Mean and Standard Deviation

Resolution and contrast are two important indicators for evaluating the quality of ultrasound imaging. In order to improve both indicators of ultrasound imaging, the ultrasound imaging method based on mean and standard deviation are proposed. Through simulation results of multiple scattering points at different depths, the proposed method achieves a lateral resolution of 50.50% compared to delay and sum (DAS) and 36.17% compared to square-neighborhood robust signal mean-to-standard-deviation factor imaging (SN-RSMSF). Through the simulated anechoic and hyperechoic regions results, the contrast improvement of the proposed method can reach up to 0.36dB, compared to DAS and SN-RSMSF.
