title: Technical trends in functional radiology of the lung.
abstract: In functional radiology of the lung, the depiction of subtle details of circulatory and bronchial anatomy, is very important. At present, the evolution of the radiographic techniques allows to overcome the difficulty in imaging, essentially related to the marked difference in density of chest structures, producing radiographs optimized to the concomitant representation of the parenchyma and higher absorption structures. Main quality factors related to radiation beam optimization on one hand and to imaging systems on the other hand, are considered with an analysis of the evolution of methods and techniques of thoracic radiology.
