本文利用仿真方法研究一种新型具有内置电极的矩形电容层析成像传感器。其由4个内置电极和12个外置电极组成。通过有限差分方法求得普适的矩形敏感图分布，并进一步对其进行处理得到针对这种特殊传感器的专门敏感图。对三种典型的物质分布进行了成像研究，并与无内置电极的12电极测量装置进行比较。计算结果显示了具有内置电极的传感器比无内置电极传感器具有更高的成像质量。

A square ECT sensor with internal electrodes was simulated andassociated sensitivity maps were constructed for image reconstruction. The performances of it were evaluated using linear back projection and iterative algorithms. Results were compared against previously investigated square sensor without internal electrodes, and it was found that the sensor with internal electrodes was able to produce improved images particularly for objects with sharp corners and flat surfaces, which can be a significant advantage for imaging the well-known core-annulus structure of solids distribution in circulating fluidized bed combustors.
