电阻抗断层成像(EIT)是一种医学成像技术，通过皮肤上的电极施加低频、低幅度的电磁场来计算体内的电导率和/或介电常数，并根据重建的值形成函数图像。这项工作描述了计算EIT衍生的肺功能替代测量的方法，并从功能EIT图像中识别空气滞留和固结的区域。这些方法是为患有囊性纤维化的儿科患者开发的，对他们来说，实时非电离成像方式对监测疾病进展或肺恶化有很大好处。
Electrical impedance tomography (EIT) is a medical imaging technique in which low frequency, low amplitude electromagnetic fields applied through electrodes on the skin are used to compute the conductivity and/or permittivity inside the body and form functional images from the reconstructed values. This work describes methods of computing EIT-derived surrogate measures of pulmonary function and identifying regions of air trapping and consolidation from functional EIT images. These methods were developed for pediatric patients with cystic fibrosis, for whom a real-time non-ionizing imaging modality can be of great benefit for monitoring disease progression or a pulmonary exacerbation.
