The diagnostic limitations of postero-anterior films of the chest and the value of standardizing lordotic and oblique projections are discussed.
A relatively simple method for obtaining predetermined angulation roentgenograms is presented.
Types of angulation apparatus are described for both lordotic and oblique films.
The possibilities of this method of chest roentgenography in obscure chest lesions is demonstrated.

Angulation films will in many instances eliminate the necessity for tomograms. [See FIGURE 7and FIGURE 8 in Source pdf]
