Figure 4From: Conductivity image enhancement in MREIT using adaptively weighted spatial averaging filter Experiment results for the upper abdominal region. (a) Computed values of the denominator h in (7) for the upper abdominal region in Figure 2(a). (b) Conductivity image without using any filtering. (c) Filtered conductivity image by the iteration method in (16). (d) Conductivity image after applying the adaptively weighted spatial averaging filter.Back to article page
