title = "Higher order versus second order statistics in ultrasound image deconvolution",
abstract = "We recently proposed a method for the estimation of imaging distortions associated with ultrasound images, based on the higher-order statistics (HOS) of radio frequency data. In this correspondence, we utilize the HOS-based estimated distortions to deconvolve ultrasound images of the breast. We also estimate imaging distortions based on the second-order statistics (SOS) of radio frequency ultrasound data and subsequently utilize them to deconvolve the same breast images. Both subjective and objective measures suggest that deconvolution with HOS-based distortion estimates led to significantly higher resolution gains as compared to the gains achieved when SOS-based distortion estimates were used.",

note = "Funding Information: The observed ultrassound image can be considered as a distorted version of the ixue tissue information. Along the axial direction the distortion is dominated by the pulse-echo wavelet of the imaging system, while along the lateral direction the distortion is mainly due to finite-width lateral beam profile. Provided that these distortions are known in advance, or non-invasively measurable, their effects can be compensated for in the observed image. Vl'ith propagation in tissue, however, both axial and lateral distortions change due to the inhomogeneities of the media and the geometry of the imaging system.
