摘要

本文研究了相干超声平面波合成(SCE-CPWC)中同步编码发射的概念。在此基础上，我们解除了证明SCE-CPWC有效的约束条件，并证明了使用11 -正则化可以获得对失谐介质的良好估计。给出并讨论了散射体稀疏分布和密集分布介质的模拟结果。

Inverse problem approaches for coded high frame rate ultrasound imaging

In this paper the concept of Simultaneous Coded Emission in the context of Coherent ultrasound Plane Wave Compounding (SCE-CPWC) is studied. The constraints under which SCE-CPWC was proven to be effective are released and we show that a good estimation of the insonified medium can be obtained using l1-regularization. Simulation results on medium with sparse and dense distribution of scatterers are presented and discussed.
