A New Reconstruction Approach in Diffraction Ultrasound Tomography: Combine Transmission Mode with Reflection Mode Tomography

摘要

Diffraction Ultrasound Tomography based on Fourier scattering theorem is studied. In this paper, we reveal the relation between the transmission mode (TMDT) and the reflection mode diffraction tomography (RMDT).Different from the transmission mode ultrasound tomography which lose the details of the picture, We combine the forward scatter field data and the backward data with the higher frequency information. The iterative reconstruction method with forward non-uniform fast Fourier transform(NUFFT) is used in the proposed algorithm. The simulation result indicates that the algorithm proposed in this paper is obviously improve the reconstruction quality than the TMOT or the RMDT.
