Evaluation of a quality control phantom for digital chest radiography
RATIONALE AND OBJECTIVES To examine the effectiveness and suitability of a quality control (QC) phantom for a routine QC program in digital radiography. MATERIALS AND METHODS The chest phantom consists of copper and aluminum cutouts arranged to resemble the appearance of a chest. Performance of the digital radiography (DR) system is evaluated using high and low contrast resolution objects pla...
متن کاملThe Practice of Chest Radiography Using Different Digital Imaging Systems: Dose and Image Quality
Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality. Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...
متن کاملBeliefs and behaviors of radiographers concerning “Digital Chest Radiography”
Aims Chest radiography is the first choice for the investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible for managing the radiation exposure to patients and providing adequate image quality according to the ALARA concept. The knowledge and experience of radiographers in performing chest radiography helps to improve the diagnosis of diseases. The aim...
متن کاملPatient effective dose evaluation for chest X-ray examination in three digital radiography centers
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
متن کاملOptimization of chest radiographic imaging parameters: a comparison of image quality and entrance skin dose for digital chest radiography systems.
We studied the performance of three computed radiography and three direct radiography systems with regard to the image noise and entrance skin dose based on a chest phantom. Images were obtained with kVp of 100, 110, and 120 and mA settings of 1, 2, 4, 8, and 10. Significant differences of image noise were found in these digital chest radiography systems (P<.0001). Standard deviation was signif...
