A Quality Control Test for General X-Ray Machine
Languages of publication
The aim of a quality assurance program is to assist a radio-diagnostic facility in consistently obtaining adequate radiological information with a minimum of dose and a minimum of cost. An integrated part of a quality assurance program is quality control ascertaining quality by measurements and other procedures. When procuring equipment, a specification is worked out taking into account all aspects of the performance of the equipment including the desired tolerances of technique factors. In this study the seven tests (beam alignment, beam collimation, reproducibility, accuracy of kv, time accuracy, half value layer (HVL) and leakage) were carried out for the newly installed General X-Ray machine at Nuclear Malaysia and were in the acceptable limits. Such a test will be the responsibility of a qualified physicist or engineer. The status test is carried out in order to establish the functional status of the equipment. The test is performed immediately after the acceptance test or as an integrated part of it. The test will be repeated when repair influencing the functional status has taken place like the acceptance test; the status test will comprise absolute measurements and will likewise be the responsibility of a qualified physicist or engineer.
