Data And Results For Manuscript "Multi-Frequency Electrical Impedance Tomography As A Non-Invasive Tool To Characterize And Monitor Crop Root Systems "

Root systems are essential in nutrient uptake and translocation, but are difficult to characterize non-invasively with existing methods. We propose electrical impedance tomography (EIT) as a new tool for the imaging and monitoring of crop root systems. In a laboratory experiment we demonstrate the capability of the method to capture physiological responses of root systems with high spatial and temporal resolution. We conclude that EIT is a promising functional imaging technique for crop roots. This package contains measured raw EIT data, electrical imaging results, spectral results from the Debye decomposition, and the Python scripts used to generate the plots in the manuscript.植物根系在养分吸收与转运过程中发挥着不可或缺的作用，但现有技术手段难以对其开展非侵入式的特征表征。我们提出将电阻抗断层成像（electrical impedance tomography, EIT）作为作物根系成像与监测的新型工具。本研究通过实验室实验验证了该方法可在高时空分辨率下捕捉根系的生理响应特征。综上，EIT是一种极具应用前景的作物根系功能成像技术。 本数据集包包含实测原始EIT数据、电阻抗成像结果、德拜分解（Debye decomposition）光谱结果，以及用于生成论文附图的Python脚本。
