Abstract
The American National Standard Method for the Sensitometry of Medical and Dental X-ray Films, PH2.9, provides standard methods for measuring the speed and average gradient of medical and dental x-ray films. The most recent revision of this standard was completed this year. While the response of a film can be measured by this standard method, there are no provisions for measuring the response of an intensifying screen or of a screen-film combination. Therefore, the sensitometric parameters of the film are of limited utility to users of screen-film combinations. In an attempt to correct this situation, a task force was established last year by Subcommittee PH2-31 of the American National Standards Institute (ANSI) to pursue the establishment of a new and separate standard providing a method for the direct measurement of the response of screen-film-processing combinations. This paper is a report on the status of the work of that task force.
