论文摘要
电气成像和弹性成像是一套不同应用,包括医疗断层扫描,非破坏性测试和结构健康监测的有希望的方式。这些新兴方式能够提供遥远,无创和低成本的机会。不幸的是,这两种模式都是严重的非线性反问题,对噪声和建模误差的影响。然而,合并免费数据集的能力同时获得了互惠信息。通过将电和弹性方式融合为关节问题,我们可以通过利用来自模态和联合结构操作员的辅助信息来稳定反转过程。在这项研究中,我们将讨论一种将电和弹性成像结合在关节重建问题中的可能方法,从而引发了新型的多模式应用,以在医学和结构工程中使用。
Electrical and elasticity imaging are promising modalities for a suite of different applications including medical tomography, non-destructive testing, and structural health monitoring. These emerging modalities are capable of providing remote, non-invasive, and low cost opportunities. Unfortunately, both modalities are severely ill-posed nonlinear inverse problems, susceptive to noise and modelling errors. Nevertheless, the ability to incorporate complimentary data sets obtained simultaneously offers mutually-beneficial information. By fusing electrical and elastic modalities as a joint problem we are afforded the possibility to stabilise the inversion process via the utilisation of auxiliary information from both modalities as well as joint structural operators. In this study, we will discuss a possible approach to combine electrical and elasticity imaging in a joint reconstruction problem giving rise to novel multi-modality applications for use in both medical and structural engineering.
