    Abstract:
    We have constructed compensating screens which have different sensitivities for the pulmonary hilum and mediastinum in contrast to the lung. With these screens the regions of the mediastinal and retrocardiac areas are simultaneously displayed with optimal contrast on postero-anterior (PA) chest radiographs. The potential clinical use of compensating screens was evaluated in 67 patients for visibility of the anatomical structures in comparison with conventional screens. Confidence test was used to compare the detectability of the various anatomical structures of the chest. The chest radiographs obtained with compensating screens improved visibility of the anatomical structures including the tracheal bifurcation, right and left main bronchus, and paraesophageal line.
