1. An ultrasound probe with sub-aperture processing capable of dynamic focus, comprising:

  • an array of transducer elements that forms a sub-aperture in the ultrasound probe, an initial delay being applied to ultrasound signals associated with the transducer elements of the sub-aperture, and the transducer elements being assigned to dynamic delay update groups, anda sub-aperture processor configured to dynamically apply delay updates to the ultrasound signals repeatedly for a predetermined time period to approximate an ideal delay profile, the delay updates being configurable per sub-aperture processor and a magnitude of the delay updates being dependent on the dynamic delay update groups to which the transducer elements are assigned.
