  • Method for imaging of nonlinear interaction scattering
    Patent number: 11209530
    Abstract: 1st and 2nd pulsed waves (103, 104) with 1st and 2nd center frequencies are transmitted along 1st and 2nd transmit beams so that the 1st and 2nd pulsed waves overlap at least in an overlap region (Z) to produce nonlinear interaction scattering sources in said region. The scattered signal components from at least the nonlinear interaction scattering sources are picked up by a receiver (102) and processed to suppress other components than said nonlinear interaction scattered signal components, to provide nonlinear interaction measurement or image signals. At least a receive beam is scanned in an azimuth or combined azimuth and elevation direction to produce 2D or 3D images of said nonlinear interaction scattering sources.
    Type: Grant
