Chest radiography

plays an essential role in the

diagnosis

of

thoracic

disease

and

is

the

most

frequently

performed

radiologic

examination

in

the

United

States.

Since

the

discovery

of

X

rays

more

than

a

century

ago,

advances

in

technology

have

yieled numerous improvements in thoracic imaging.

Evolutionary progress in film-based imaging has led

to the development of excellent screen-film systems

specifically designed for chest radiography.
