Abstract

Different current patterns used in electric-current computed tomography (ECCT) were compared for their sensitivity to noise. This comparison was made by examining the error produced in reconstructing one voltage pattern from measurements made using another. It was found that the adjacent-pair current pattern is more sensitive to noise than spatial trigonometric current patterns. The measured spatial trigonometric voltage patterns were not degraded when a simulated electrode contact impedance was introduced.
