<title>Quality Control In Diagnostic Radiology</title>

Abstract

The factors that I consider to be absolute essentials in our quality control program at Mayo Clinic are x -ray generator calibration, sensitometric regulation of film processing, x -ray exposure technique system, and on -line quality control. Other aspects of a complete system such as measurement of x -ray tube focal spot size, radiation output checks, checks on the performance of our image systems, and evaluation of new products are desirable to improve our work; these have been incorporated as they have become available. An effective quality control program can minimize patient exposure, can improve and maintain the overall diagnostic quality of the radiographs accepted for interpretation, and can save money in the institution.X-ray generators can be calibrated to produce essentially the same radiographic results with the same exposure factors. It is difficult, but it is generally possible, to do so within reasonable limits of about ±2 kVp.

General radiographic patient dose monitoring using conformity test data

“…The ESAK value can be used to determine the amount of exposure dose which refers to the national I-DRL value, as stated in the Decree of the Head of BAPETEN No. 1211/K/V/2021 concerning the Determination of Indonesian Diagnostic Reference Level Values for X-ray Ct Scan and General Radiography Modalities (Ratnawati et al, 2019;Winkler, 1976). Where in this decision the ESAK value for Chast PA is 0.4 mGy, so the ESAK value in this study still meets the national I-DRL value (Proost & Meijer, 1992;Bonello et al, 2009).…”
