测量了22名女性志愿者超声脉冲在乳腺组织中传播时的位相像差。这些实验旨在评估这些像差对不同换能器和成像几何形状的临床超声图像质量的影响。给定患者的位相像差曲线与从该患者的乳房X光照片中确定的实质组织的数量相关。这些数据有助于评估常规超声成像系统的图像质量，以及自适应超声成像系统的潜在应用。结果表明，对于典型的换能器频率和大小，相位像差显著降低了乳房图像的质量。
The phase aberrations encountered by ultrasonic pulses propagating through breast tissue in twenty-two female volunteers were measured. The experiments were designed to assess the impact of these aberrations on clinical ultrasonic image quality for a variety of transducer and imaging geometries. The phase aberration profiles of a given patient were correlated with the amount of parenchymal tissue determined from that patient's mammogram. These data are useful in assessing the image quality achievable with conventional ultrasonic imaging systems, and the potential application of adaptive ultrasonic imaging systems. The results indicate that phase aberrations significantly degrade breast image quality for typical transducer frequencies and sizes.
