GREIT Reconstruction for an neonate human thorax geometry

Data

Data are available Here. Data were recorded from a 10-day old spontaneously breathing neonate lying in the prone position with the head turned to the left, as documented in: S. Heinrich, H. Schiffmann, A. Frerichs, A. Klockgether-Radke, I. Frerichs, Body and head position effects on regional lung ventilation in infants: an electrical impedance tomography study. Intensive Care Med., 32:1392-1398, 2006.

Use Elliptic GREIT model

The shape of a neonate is roughly elliptical. Based on the neonate CT here, the elliptical ration is about 1:1.14.
