Radiation exposure and dose evaluation in intraoral dental radiology.
In this study, dose area product measurements have been performed to propose diagnostic reference levels (DRLs) in intraoral dental radiology. Measurements were carried out at 60 X-ray units for all types of intraoral examinations performed in clinical routine. The third quartile values calculated range from 26.2 to 87.0 mGy cm(2). The results showed that there exists a large difference between...
متن کاملAbsorbed dose to peripheral organs during different methods of dental radiology using radiation estimation models
Introduction: Dental radiography as one of the most frequent type of radiological examinations is accepted for medical investigations due to their significant benefits nevertheless using ionizing radiation. It has lower radiation dose compared to another radiological examination but because of its high application for children, radiation dose needs attention. Based on affectin...
متن کاملMeasurement of dose in panoramic dental radiology.
The National Radiological Protection Board (NRPB) has recommended the introduction of dose-width product (DWP) for the measurement of patient dose in panoramic dental radiology and has proposed a reference level of 65 mGy mm for adult exposures. This paper describes a method for measuring DWP and dose-area product (DAP) using thermoluminescent dosemeters (TLDs). The technique was used on 16 set...
متن کاملReduced Radiation Dose in Diagnostic Radiology
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Within the past 20 years, the radiographic examination in the medical field has increased by a factor of about 3 to 5 times, while the total radiation dose has increased by a factor of about 200-400. This has ascribed to the rapid increase in CT usage (1). T...
متن کاملForeword: Radiology Select Volume 5—Radiation Dose and Dose Reduction
When we chose Radiation Dose and Dose Reduction as the topic for the fifth volume in the Radiology Select series, we were very excited about offering a compilation of articles on a theme of utmost importance to all radiologists and health care providers. The concept of the right radiation dose for the right study, at the right time, is central to optimizing care for those patients who require i...
