ICRU Report 70, Image Quality in Chest Radiography


Image quality in chest radiography is an important, but complex subject. The complicated anatomy of the chest, as well as the various ways that chest disease may manifest, require careful consideration of radiographic technique. The manner in which human observers deal with the complexity of chest images adds further dimensions to image analysis that are not found in other radiographic examinations.

This Report describes many issues that are related to the quality of chest radiographic images. In so doing, it relies upon the very extensive literature on this topic, a topic that has been one of the most thoroughly studied in all of radiography. Strategies that are generally agreed to improve the quality of chest radiographs are described, as are approaches to the assessment of image quality.
