摘要

生物组织电学特性的体内估计在一些医学应用中是相关的，从热疗治疗计划到剂量测定。在这篇文章中，我们提出了一种新的逆散射方法来解决这个问题。特别是，该方法基于对磁共振扫描仪中获得的无相$\boldsymbol{B}_{1}^{+}$测量值进行逆变。此外，它还利用了一种创新的利用磁共振图像衍生的分割解剖模型来正则化逆散射问题。

Electrical Properties Mapping via Segmented and Phaseless Contrast Source Inversion

In-vivo estimation of electrical properties of biological tissues is relevant in several medical applications, ranging from hyperthermia treatment planning to dosimetry. In this contribution, we propose a novel inverse scattering approach addressing this problem. In particular, the approach is based on inverting phaseless $\boldsymbol{B}_{1}^{+}$ measurements acquired in a magnetic resonance scanner. Moreover, it takes advantage of an innovative use of the segmented anatomy model derived by magnetic resonance images in order to regularize the inverse scattering problem.
