Analysis of an image quality assurance program.

Reject film analysis before and after the introduction of a quality assurance program showed a 45% decrease in rejected films. The main changes in equipment and routines were: Increased control of film processors and X-ray generators. New film cassettes and screens. Decreased number of film sizes. Information to and supervision of radiographing personnel. Savings in costs and increased income from an increased amount of out-patients corresponded to about 4.5% of the total cost of operating and maintaining the department.
