Patient 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 کاملX-ray detectors for digital radiography.
Digital radiography offers the potential of improved image quality as well as providing opportunities for advances in medical image management, computer-aided diagnosis and teleradiology. Image quality is intimately linked to the precise and accurate acquisition of information from the x-ray beam transmitted by the patient, i.e. to the performance of the x-ray detector. Detectors for digital ra...
متن کاملSurvey of the Use of X-ray Beam Collimator and Shielding Tools during Infant Chest Radiography
Background The use of shielding tools and X-ray beam collimator has extensively been advocated as effective methods to reduce radiation exposure to patients underwent radiological procedures. The aim of this study was to address the use of these protection measures during infant chest radiography. Material and Methods 348digital and/or analogue infant chest radiographs were reviewed that perfor...
متن کامل[Optimization of X-ray conditions for full spine X-ray examinations in slot-scan digital radiography].
The purpose of this study was to optimize X-ray conditions for full spine X-ray examinations in slot-scan digital radiography (SSDR). Follow-up of spinal deformities, such as scoliosis, typically involves many radiographs of the patient throughout childhood and adolescence. The Radiation doses for the full spine X-ray examination should be minimized. Recently, SSDR has been introduced for full ...
متن کاملX-Ray Radiography of EB Welded Joints in India
Electron Beam welding is becoming more important in Indian industries due to the growing automation of the process and superior weld quality, resulting from virtually zero heat affected zone (HAZ). Two main types of defects are often encountered in EB welding joints viz void type defects and crack type. EB welding joints must be radiographically inspected for all these types of defects and it i...
