title: Method for comparing films and processing procedures in photofluorography.
abstract: A method for comparing measurements of films and processing procedures is described. A stepped wedge is developed on basis of density measurements in defined areas of chest photofluorographic films. Quality criteria for films and processing procedures are established by systemization of film evaluation. Minor modifications of the method are necessary for application elsewhere in diagnostic radiology.
