“…Ghana is not alone in experiencing these problems: similar findings were also identified in Nigerian hospitals, leading to higher radiation doses in some hospitals. A study in Nigeria in sub‐Saharan Africa ( 22 ) which assessed the accuracy in patient positioning, beam collimation, and identification of radiographs as indicators for quality assurance and radiation protection, showed that positioning and beam collimation contributed to a high percentage of unnecessary radiation dose to the patients in all the participating hospitals. The authors suggested that poor practice of radiation protection exists in the hospitals in Nigeria, and that most patients were at risk of having other parts of the body not involved in the required X‐ray examination exposed to radiation.…”

Pelvis X‐ray examinations inevitably involve exposure of the gonads to ionizing radiation. In line with the principle of keeping doses as low as reasonably practicable (ALARP), accurate patient dose measurement is vital if we are to ascertain that these exposures are fully optimized. The study aimed to provide patient dose estimates for pelvis examination being undertaken at 10 separate hospitals in Ghana in order to provide an initial quantitative indication of each site's typically achievable radiation safety and quality standards. The method employed was adapted from established methods and peer reviewed literature, such as the International Atomic Energy Agency (IAEA) publications on optimization of the radiological protection of patients undergoing radiography, fluoroscopy, and computed tomography examinations in some countries in Africa, Asia, and Eastern Europe. Dose measurements were calculated on 323 patients (137 (42%) male, 186 (58%) female, ages, 38.56 yr ±9.0; range 20–68). The entrance surface dose (ESD) was determined by an indirect method, using the patient's anatomical data and exposure parameters utilized for the specific examination. The Quality Assurance Dose Database software (QADDs) developed by Integrated Radiological Services Ltd. in Liverpool, UK was used to generate the ESD values. The study identified variations in the technique factors used compared with the recommendations in the European Commission (EC) quality criteria. Eighty percent of the hospitals recorded lower ESD values below IAEA recommended diagnostic reference levels (10 mGy) and 40% of the hospitals exceeded the UK national reference value (4 mGy). However, one hospital consistently recorded higher ESDs than the other hospitals. The variations in the data recorded demonstrate the importance of creating awareness by the radiographic staff on quality assurance and standardization of protocols to ensure satisfactory standards and optimized radiation dose to patients and staff.PACS number: 87.59.B

The quality control tests' methods, as well as the criteria for scoring the results, are in full agreement with those specified in the American Association of Physicists in Medicine (AAPM) Report No.4 and IEC 61223-3-1 (AAPM, 1981; IEC 61223-3-1, 1999 (Bouzarjomehri, 2004; Ciraj et al., 2005; Ramanandraibe, 2009; Papadimitriou, 2001; Shahbazi-Gahrouei, 2006). Some investigators focused only patient dose optimization (Brix et al., 2005; Vano& Fernandez, 2007; Seibert, 2004; Williams &Catling, 1998), whereas the others examined both the patient dose and image quality in radiographic devices (Aldrich et al., 2006; Schaefer-Prokop et al., 2008; Geijer, 2002). There are also studies that give reference values for clinical x-ray examinations by measuring phantom dose (Gray et al., 2005) . But there is no any study focused to the dose optimization during quality control tests of x-ray devices. Dose optimization is very important because of the quality and quantity of quality control tests of x-ray equipmentconclusion this study shows that optimization of technical factors may lead to a substantial dose reduction. If the optimized parameters are applied to X-ray equipment during quality control tests, it is possible to determine how much good image quality will be obtained with this optimized parameters and how much dose will be measured when this qualified image is developed. The results show the importance of radiographic staff training about the recommended parameters that are applied to the x-ray units for a qualified quality control system. It is essential to provide relevant education and training to staff in the radiology departments.It can be sure that with such a study the questions on many professional staff's mind will be answered, and the dose and the image characteristics will be parameters that are controlled and managed.
