摘要
研究了单电流源电阻层析成像的电流激励模式。采用统一的电压测量策略,研究了16电极电阻层析成像系统的8种电流激励模式,比较了不同激励模式对应的等势线分布、独立测量数、测量电压动态范围以及重建图像质量。综合分析上述指标,激励模式7(准对角激励)为最优电流激励模式。
The current exciting mode for electrical resistance tomography（ERT） was studied.Eight current e- xciting modes for a 16-electrode ERT system were researched using uniform voltage measurement strate- gy.The isopotential line distribution,the number of independent measurement,measured voltage dynamic range and reconstructed image quality of these eight modes were compared,through which quasi opposite current drive pattern was obtained.
