Abstract

We give criteria for the distinguishability of two different conductivity distributions inside a body by electric current computed tomography (ECCT) systems with a specified precision. It is shown in a special case how these criteria can be used to determine the measurement precision needed to distinguish between two different conductivity distributions. It is also shown how to select the patterns of current to apply to the body in order to best distinguish given conductivity distributions with an ECCT system of finite precision.

摘要

我们给出了通过特定精度的电流计算机断层成像（ECCT）系统区分体内两种不同电导率分布的标准。在特殊情况下，展示了如何使用这些标准来确定区分两种不同电导率分布所需的测量精度。还展示了如何选择要施加到身体上的电流模式，以便使用具有有限精度的 ECCT 系统最佳地区分给定的电导率分布。
