提出了一种利用四个线阵探头配置的四边形观测数据的超声逆散射成像技术，旨在建立一种实用、通用、低成本、高速数据采集的逆散射成像系统。在本方法中，基于傅里叶衍射投影定理，将后向和侧向散射波数据以及传统的前向散射数据纳入重建计算中。尽管由于有限的四边形观测以及线阵的有限孔径而难以解决逆散射问题，但通过仿真证明了该方法的有效性。
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.
