Abstract

Quality control (QC) tests play a crucial role for patients' dose management in diagnostic radiography. X-ray tube focal spot size is the most important index for QC of x-ray machines. The focal spot size is typically estimated using pinhole or the star pattern. However, the results by such the techniques are rather subjective. This disadvantage could be decreased in digital radiography when an image brightness distribution histogram is in use. Average value of brightness correlates to the focal spot size (significance 0.99). This technique does not require any test object. The results demonstrate that the above approach could become an important part of the QC for digital x-ray diagnostic radiography equipment. [ABSTRACT FROM AUTHOR]

Abstract

This EFOMP Policy Statement is an update of Policy Statement No. 6 first published in 1994. The present version takes into account the European Union Parliament and Council Directive 2013/55/EU that amends Directive 2005/36/EU on the recognition of professional qualifications and the European Union Council Directive 2013/59/EURATOM laying down the basic safety standards for protection against the dangers arising from exposure to ionising radiation. The European Commission Radiation Protection Report No. 174, Guidelines on Medical Physics Expert and the EFOMP Policy Statement No. 12.1, Recommendations on Medical Physics Education and Training in Europe 2014, are also taken into consideration. The EFOMP National Member Organisations are encouraged to update their Medical Physics registration schemes where these exist or to develop registration schemes taking into account the present version of this EFOMP Policy Statement (Policy Statement No. 6.1"Recommended Guidelines on National Registration Schemes for Medical Physicists")., (Copyright © 2016.
