Patent ID: 7967753

Claim:
A method for non-linear ultrasound imaging of a patient's body, comprising: transmitting ultrasound excitation pulses of alternating polarity into the patient's body; receiving ultrasound echo signals in response to the excitation pulses; and applying a weighting scheme to the received ultrasound echo signals, wherein the weighting scheme is given by ∑ t = 1 n ⁢ ⁢ a · P t + / - + b · P t + 1 - / + + c · P t + 2 + / - where t is an index of summation incremented by 1, t and t+1 indicate neighboring pulse responses, P +/− and P −/+ are echo signals in response to excitation pulses of opposite polarities, n is an upper bound of summation and n is 3 or larger, and a, b, and c equal 1, 2, and 1, respectively.
