Comparison of Drive Patterns for Single Current Source EIT in Computational Phantom

摘要：

Electrical impedance tomography (EIT) estimated the electrical conductivity distribution within a body. Bipolar drive pattern appeared in most EIT studies that the current was injected with a single current source and sink. In the present study, we built a computational phantom and compared the quality of dynamic EIT image in terms of data quality, resolution and anti-noise performance associated with three different bipolar drive patterns: polar drive pattern, pseudo-polar drive pattern and adjacent drive pattern. The results demonstrated that the pseudo-polar drive pattern is optimal.
