扭曲Born衍射层析成像：逆非圆形无限弹性管散射超声场的局限性及其应用
Distorted Born Diffraction Tomography: limits and applications to inverse the ultrasonic field scattered by an non-circular infinite elastic tube
摘要：
本文研究了超声衍射层析成像技术在非圆二维圆柱体中的应用。用变形玻恩迭代法求解逆散射问题属于代数构造算法类。这种方法的目的是提高Born近似的应用范围（在弱对比介质的情况下）。这就产生了关于散射体的定量信息，例如声速和时间。这种定量超声成像技术在医学、水声和无损检测等领域具有很大的应用价值。
英文摘要：
This study focuses on the application of ultra sonic diffrac tion tomography to noncircular 2D-cylindri - cal ob jects im mersed in an in fi nite fluid. The dis torted Born it er a tive method used to solve the in verse scat ter ing prob lem be longs to the class of al ge braic re con struc tion al go rithms. This method was de vel - oped to in crease the or der of ap pli ca tion of the Born ap prox i ma tion (in the case of weakly-con trasted me dia) to higher or ders. This yields quan ti ta tive in for ma tion about the scat terer, such as the speed of sound and the at ten u a tion. Quan ti ta tive ul tra sonic im ag ing tech niques of this kind are of great po ten tial value in fields such as med i cine, un der wa ter acous tics and non de struc tive test ing.
