title: Quality assurance of the bedside chest radiography process.
abstract: The bedside chest radiography process was analyzed in terms of modern quality management guidelines and the sources of quality problems were identified. In order to analyze systematically the various quality factors, the process was described in a top-down fashion with the aid of data flow diagrams. Two internal quality control points and one external point were found in the process. Means to measure quality at the quality control points including questionnaires and a formula for calculating the internal quality index were developed.
