| 英文摘要 | Ultrasound diffraction tomography based on Fourier scattering theorem of the lossless circumstance is studied. The relation between resolution and imaging quality is analyzed and a reconstruction algorithm in frequency domain is proposed to reduce storage and computation. Different from an iterative reconstruction method based on NUFFT, we put forward a novel algorithm of interpolation based NUFFT, which compute the equispaced results from the non-uniform samples of two nearest projection lines using linear angular interpolation. The simulation result indicates that the algorithm proposed in this paper is much better than filtered-backprojection algorithm. With the projection data increase, reconstruction will approximate to the optimal. |
