Using GafChromic film to estimate the effective dose from dental cone beam CT and panoramic radiography.
OBJECTIVES To demonstrate the feasibility of GafChromic(®) XR-QA2 (ISP Corp., Wayne, NJ) as a dosemeter when performing measurements of the effective dose from three cone beam CT (CBCT) units and to compare the doses from examinations of three common dental clinical situations. A second aim was to compare the radiation doses for three digital panoramic units with the doses for the CBCT units. ...
متن کاملEffective dose from cone beam CT examinations in dentistry.
Cone beam CT (CBCT) is becoming an increasingly utilized imaging modality for dental examinations in the UK. Previous studies have presented little information on patient dose for the range of fields of view (FOVs) that can be utilized. The purpose of the study was therefore to calculate the effective dose delivered to the patient during a selection of CBCT examinations performed in dentistry. ...
متن کاملPatient Dose-Area Product (DAP) Monitoring in Digital Radiography
The objective of this study was to determine the Dose Area Product (DAP) for sample of 70 patients (40 Females and 30 Males) undergoing different types of digital radiography (DR) examinations at King Abdul-Aziz University Hospital (KAUH), Saudi Arabia. This study was done through implementing a quality control (QC) program initiated by The Center for Training and radiation protection, KAU. It ...
متن کاملEstimating and comparing the radiation cancer risk from cone-beam computed tomography and panoramic radiography in pediatric and adult patients
Background: This study aimed to estimate and compare the absorbed dose, lifetime cancer risk and mortalities due to cone-beam computed tomography (CBCT) and panoramic examinations on patients. Materials and Methods: The exposure factors were applied to 332 patients in two age groups (6-10, and ˃18-year-old). The dose-area product (DAP) values were measured for CBCT and panoramic radiographies. ...
متن کاملEvaluation of Factors Affecting Absorbed Dose, Optimization Methods and Patient Dose Reduction in Dental Cone Beam CT (CBCT)
Introduction: Nowadays the use of cone beam computed tomography in dental imaging is increasing, although this method has a much lower dose than conventional CT scans, it delivers a higher dose than the panoramic and periapical patients therefore, , the aim of this study was to investigate the factors affecting the patients' dose in dental CBCTs and methods of optimizing and reducing the patien...
