Abstract:
In an ultrasound system for imaging structure within a subject, an apparatus for generating a compounded image frame having reduced motion artifacts, said apparatus comprising:a front-end for transmitting temporally distributed ultrasound waves into the structure and, for at least one sample volume location within an image plane of the structure, forming over time a set of received beams temporally separated in response to ultrasound waves backscattered from the structure, said set of received beams intersecting at said sample volume location; and a processing module receiving said set of received beams and generating a compounded data value corresponding to said at least one sample volume location within said image plane based on said set of received beams, said processing module forming a compounded image frame from at least one said compounded data value, wherein said set of received beams intersecting at said sample volume location are formed in less than a single frame time.
