摘要：
本文对延迟求和（DAS）、滤波延迟乘加（DMAS）、最小方差（MV）和镜面接收波束形成方案在镜面反射体超声成像中的表现进行了比较。研究的主要贡献包括：1）通过实验研究，对平面反射体在不同倾斜角度以及位于介质中不同深度时四种接收波束形成方案的性能进行比较；2）研究MV波束形成中子阵列长度对镜面结构成像的影响。定性结论通过对比度和广义对比噪声比进行了定量验证。本研究考察了每种接收波束形成技术的优缺点，并强调了针对应用定制的波束形成方案对镜面结构成像的重要性。
英文摘要：
This work presents a comparison of the delay and sum (DAS), filtered delay multiply and sum (DMAS), minimum variance (MV) and specular receive beamforming schemes in the context of ultrasound imaging of specular reflectors. The main contributions of the study are, 1) a performance comparison of the four receive beamforming schemes through experimental studies for varying angulations of planar reflectors and for reflectors located at varying depths in the medium and, 2)an investigation on the influence of the sub-array length in MV beamforming on the imaging of specular structures. The qualitative conclusions are quantitatively validated in terms of contrast and generalized contrast-to-noise ratios. The study examines the benefits and drawbacks of each receive beamforming technique and highlights the significance of application-tailored beamforming schemes for imaging specular structures.
