摘要

我们报告使用射频光学原子磁强计进行磁感应层析成像测量。我们演示了在室温和无背景减法的无屏蔽环境中，在传感器附近放置不同电导率的虚拟目标的成像。系统产生的图像准确地再现了实际物体的特征。此外，我们进行了有限元模拟，以评估用我们的系统测量低电导率生物组织的潜力。我们的研究结果证明了一种基于光学原子磁强计的仪器用于生物样品磁感应断层成像的可行性，特别是用于绘制心脏异常电导率。

Optical atomic magnetometry for magnetic induction tomography of the heart

We report on the use of radio-frequency optical atomic magnetometers for magnetic induction tomography measurements. We demonstrate the imaging of dummy targets of varying conductivities placed in the proximity of the sensor, in an unshielded environment at room-temperature and without background subtraction. The images produced by the system accurately reproduce the characteristics of the actual objects. Furthermore, we perform ﬁnite element simulations in order to assess the potential for measuring low-conductivity biological tissues with our system. Our results demonstrate the feasibility of an instrument based on optical atomic magnetometers for magnetic induction tomography imaging of biological samples, in particular for mapping anomalous conductivity in the heart.
