To study the anatomical precision of EIT images, we compared 2D, 2.5D and 3D thorax models of varying complexity for EIT data of a healthy and an injured lung. We determined the lung shape as the averaged tidal image for several breaths. The overlap was computed for a reference CT shape. A 3D subvolume of the lung with large anatomical complexity achieves the best overlap scores for most cases.
