A radiographic method to estimate lung volume and its use in small mammals

In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V*L = 0.496 · V RX ≈ 1/2·V RX , where V RX is a measurement obtained fr...
