- W1975133026 abstract "The influence of wave-front distortion in ultrasonic imaging is examined using a model that represents the signal in the imaging system aperture in terms of the aperture, the scattering source, and a distortion function. This model, along with assumptions that the beam pattern factors into the product of axial and lateral functions and that the distortion is represented by a time shift that is either a sinusoid or Gaussianly distributed, permits the development of expressions for the correlation function of the aperture and, thus, the intensity of the beam pattern. Although these assumptions are idealizations, the approach yields relatively simple expressions that show the way time delay couples into beamwidth to degrade resolution. Further simplifications follow from assuming that the distortion is small or that the axial and lateral beam functions have specific forms such as Gaussian shapes. The analysis indicates that compensation of distortion using time delays estimated from cross correlation of signals on adjacent elements of an aperture maximizes overall average intensity in an image of uncorrelated scatterers. The results provide representations of distortion in ultrasonic imaging systems and may be used to study the relationship between techniques that compensate for wave-front distortion." @default.
