Abstract
An ultrasound system and method for aberration correction processing in conjunction with finely pitched transducer elements and/or aberration correction processing in conjunction with a hierarchical control scheme. Results obtained from known aberration correction algorithms may be improved with the use of finely pitched transducer elements wherein the pitch of the elements (or subgroup of elements) is less than or equal to the wavelength of an ultrasound signal at the fundamental frequency. Elements of a transducer may be grouped into subgroups with aberration correction algorithms being applied to the output of each subgroup.
