The Haller Index is a measure of the extent of pectus excavatum. The Haller index is measured by means of the CT scan. It is calculated by obtaining the ratio of the horizontal distance of the inside of the ribcage and the shortest distance between the vertebrae and sternum. A Haller Index of greater than 3.25 is generally considered severe (a normal Haller Index is 2.5).
