摘要： Measurement or imaging of elastic wave nonlinear scatterers with a memory of scattering parameters comprises selecting LF pulses having characteristics to change the scattering parameters of nonlinear scatterers. A transmit time relation is selected so that the incident HF pulse propagates sufficiently close to the LF pulse that the effect of the incident LF pulse on its scatterer parameters is observed by the HF pulse. At least two elastic wave pulse complexes comprising a high frequency (HF) pulse and a selected low frequency (LF) pulse are transmitted towards the region. Received HF signals are combined to form nonlinear HF signals representing the scatterers with memory, with suppression of received HF signals from other scatterers. At least one of the received HF signals may be corrected by time delay correction and/or speckle correction with a speckle correction filter, determined by movement of the scattering object. Systems are also disclosed.

摘要： Elastic wave pulse complexes are transmitted towards said region where said pulse complexes are composed of a high frequency (HF) and a low frequency (LF) pulse with the same or overlapping beam directions and where the HF pulse is so close to the LF pulse that it observes the modification of the object by the LF pulse at least for a part of the image depth. Received HF signals are picked up by transducers from scattered and/or transmitted components of the transmitted HF pulses. The received HF signals are processed to form measurement or image signals for display, and combined in slow time to form noise suppressed HF signals or nonlinear scattering HF signals.

摘要： 1st and 2nd pulsed waves are transmitted along 1st and 2nd transmit beams where at least one of the beams is broad in at least one direction, and the transmit timing between said 1st and 2nd pulsed waves are selected so that the pulsed wave fronts overlap in an overlap region R(r,t) that propagates along at least one measurement or image curve Γ(r) in the material object. At least the scattered signal produced by nonlinear interaction between said 1st and 2nd waves in the overlap region is received and processed to form a nonlinear interaction scattering image signal along Γ(r). The measurement or image curve Γ(r) can be scanned laterally by either changing of the relative transmit timing between the 1st and 2nd pulsed waves or the direction of at least one of the 1st and 2nd transmit beams, or both. The methods are applicable to image nonlinear scattering sources for both electromagnetic and elastic waves, and combinations of these.
