Abstract

The aims of the study were to investigate the problems involved in making multifrequency EIT measurements on neonates and to compare the images obtained with the results from a group of normal adults. The Sheffield electrical impedance tomographic spectroscopy (EITS) system acquires multifrequency data using a set of eight drive and eight receive electrodes. EITS measurements were made on an inhomogeneous group of 10 neonates admitted to the special care baby unit for observation and feeding. R/S, characteristic frequency, RC and SC parameters were generated using the Cole equation. Comparisons of the parameters were made with data collected from normal adults in another study. We have shown that it is possible to obtain EITS parametric images of neonatal lungs and that there are some differences in Cole parameters between the adult and neonatal groups.

摘要

本研究的目的是调查在新生儿身上进行多频电阻抗断层成像（EIT）测量所涉及的问题，并将获得的图像与一组正常成年人的结果进行比较。谢菲尔德电阻抗断层光谱（EITS）系统使用一组八个驱动电极和八个接收电极采集多频数据。对入住特殊护理婴儿病房进行观察和喂养的10名新生儿组成的非同质组进行了EITS测量。使用科尔方程生成R/S、特征频率、RC和SC参数。将这些参数与另一项研究中从正常成年人收集的数据进行比较。我们已经表明，有可能获得新生儿肺部的EITS参数图像，并且成人组和新生儿组之间的科尔参数存在一些差异。
