Scattered Radiation in Chest Radiography

Abstract

Chest radiography is the most frequently performed radiologic study in a typical radiology department. In 1980 more than 60 million chest radiography examinations were performed in the United States, accounting for greater than one third of the total radiologic imaging procedures [Johnson and Abernathy, 1983]. The reasons for this dominant role are twofold: First, the conventional chest radiograph conveys an extraordinary amount of information about a major portion of human anatomy, including lungs, heart, major blood vessels, and substantial portions of the skeleton. These structures, which are involved primarily or secondarily in many diseases, are presented on a single image, with good spatial resolution (several line pairs per millimeter) and with good contrast provided by natural air versus soft tissue versus bone contrast relationships. Second, chest radiography can be performed simply, at relatively low cost, and with low radiation dose to the patient.
