Abstract
Introduction: Periodic monitoring of X-ray equipment quality control parameters is very important to ensure precision and accuracy of radiographic tests. Aim: The aim of this study is to assess the compliance of some quality control (QC) parameters of some conventional X-ray equipment to a known standard. Settings and Design: Setting was in Nigeria and a cross sectional design was used. Method and Material: Material used was a non-invasive digital multifunctional detector meter (MDM). Three facilities were selected from a university teaching hospital. Measurement of KVp, mAs and the exposure time accuracy was performed using MDM that incorporates computer output. The MDM was positioned at the center of the collimated beam axis with a Source to Image Distance (SID) of one meter. Eight different mAs, exposure times and KVp stations were selected and measured in each teaching hospital. Statistical Analysis: SPSS was used and statistical tools used was one way ANOVA The result obtained showed that the magnitude of deviation in KVp accuracy ranged from 0.01 to 6.07 % in all the four machines checked while the magnitude of deviation in mAs accuracy ranged from 0.00 to 19.20 %. In a similar way, exposure time accuracy deviated from 0.01 to 12.32 %. Conclusion: The study revealed that only one out of the four X-ray units at the teaching hospital in the Southern-Eastern part of Nigeria failed exposure time, mAs and KVp accuracy compliance test. K
