Correction of concentrated and distributed aberrations in medical ultrasound imaging [PDF]

open access: yes, 1996
A method is presented for iterative correction of wave fields aberrated in a plane located at an arbitrary distance from an array transducer. The signals received from the transducer are processed by an inverse extrapolator in such a way that the output ...
