不正确的边界形式已被证明会在电阻抗断层成像(EIT)图像中产生伪影。然而，如果能够将关于边界形式的信息结合到正向问题的解中，则可以实现对最终重建图像的重大改进。本文介绍了一种用于新生儿肺功能边界形态测量的新型可穿戴设备的研制。为了实现这一目标，对可用于确定边界形状的不同弯曲和挠性拉伸传感器进行了比较研究。已经研究了艾布拉姆斯Gentile Entertainment Inc.(100 Mm)、Images SI Inc.FLX02(100 Mm)和Flexpoint Inc.(50 Mm)三种不同类型的商用弯曲传感器。对弯曲传感器的可靠性和准确性进行了研究，以比较它们在边界测量中的可行性。艾布拉姆斯Gentile弯曲传感器显示出阻力和弯曲曲率的线性特性，而Flexpoint Inc.的弯曲传感器显示出阻力和弯曲曲率之间的指数关系。将介绍传感器的结果以及它们合并到传感器网络中的结果。
Incorrect boundary form has been proven to produce artifacts in electrical impedance tomography (EIT) images. However if information regarding the boundary form can be incorporated into the solution of the forward problem, major improvements to the final reconstructed image could be achieved. This paper presents the development of a new wearable device for measurement of boundary form for neonate lung function. To achieve this objective a comparative study of different bend and flexible stretch sensors that can be used for determination of boundary shape has been conducted. Three different types of commercially available bend sensors from Abrams Gentile Entertainment Inc. (100 mm), Images SI Inc. FLX02 (100mm) and Flexpoint Inc. (50 mm) have been investigated. The reliability and accuracy of the bend sensors were studied in order to compare their feasibility for boundary measurement. Abrams Gentile bend sensors show linear characteristic of resistance and bending curvature whereas the Flexpoint Inc. bend sensors show exponential relationship between resistance and bending curvature. The results of the sensors and their incorporation into a sensor net will be presented.
