Abstract

This paper describes some of the important systematic errors associated with an in-vitro study, using a four electrode impedance system, into the characteristics that allow for differentiation between normal and abnormal tissues. The impact of system parameters were investigated though the use of saline-filled phantoms and tissue samples. The latter being provided as part of a 100 patient in-vitro study carried out in collaboration with the Glenfield General Hospital, Leicester, UK. It has been found necessary to provide an environment with a known, and calibrated, post sample excision period. However, the orientation of the tissue during the measurement was also found to have a large and important impact upon the measured impedance.

在1 kHz至4 MHz频率范围内的体外研究中组织特性电阻抗测量的系统误差分析

本文描述了一些与体外研究相关的重要系统误差，使用四电极阻抗系统，进入允许正常和异常组织之间区分的特征。通过使用盐水填充的模型和组织样本，研究了系统参数的影响。后者是与英国莱斯特的格伦菲尔德总医院合作开展的100名患者体外研究的一部分。人们发现有必要提供一个已知的、经过校准的取样后切除期的环境。然而，在测量过程中，组织的取向也被发现对测量的阻抗有很大而重要的影响。
