An ultrasound inverse-scattering imaging technique using quadrangular observation data configured with four linear array probes was proposed, aiming at a practical and versatile inverse-scattering imaging system featuring low-cost and high-speed data acquisition. In the present method, backward- and sideward-scattering wave data as well as the conventional forward-scattering data were incorporated into reconstruction calculations based on the Fourier diffraction projection theorem. The validity of this method was demonstrated by simulation, despite the difficulty of solving the inverse-scattering problem due to the limited quadrangular observation as well as the finite aperture of the linear arrays.
