The Measurement of Total Lung Capacity Based on a Computer Analysis of Anterior and Lateral Radiographic Chest Images

This paper addresses the problem of computing the total lung capacity (TLC) without operator intervention by means of the picture analysis of the anterior and lateral X-ray images. Barnhard's ellipse method was employed which requires as parameters such features as the top of the diaphragm in both views, and the width of the heart in the lateral view.
