摘要： An ultrasonic diagnostic imaging system and method are provided in which aberration corrections are computed by comparing harmonic and non-harmonic images to derive aberration correction estimates. In a preferred embodiment the harmonic image provides a reference image against which aberrations in the non-harmonic image are compared. A preferred acquisition technique is to transmit at a frequency f and receive at a frequency n*f to acquire the harmonic image and to transmit at a frequency n*f and receive at a frequency n*f to acquire the non-harmonic image. In a preferred embodiment the aberration correction estimates are produced by back-propagating the image data to find the aperture correction data for the two images.
